Lab-Created Gemstone Jewellery: Natural, Synthetic and Imitation Explained
An editorial conversation between Valera Kublickis, Director of Aurum & Relics, and stylist Arthur Whitmore.
Valera: Lab-created gemstone jewellery contains material grown or made under controlled conditions rather than formed naturally. In gemmology, a synthetic counterpart has essentially the same chemical composition, crystal structure and properties as the corresponding natural gem. That differs from an imitation or simulant, which resembles another stone while being a different material. Clear descriptions should explain which material you are buying and its origin.
Arthur: The vocabulary matters because several attractive things can look similar while being quite different. A laboratory-created ruby, red glass and a natural ruby are not interchangeable descriptions. None needs an invented identity to be enjoyed. We will translate the terms into practical shopping questions, without asking a close-up photograph to perform the duties of a gemmological laboratory.

Separate identity, origin and treatment
Valera: Begin with three questions. What is the material? Was it formed naturally or produced by people? Has it received treatment that should be explained? These questions concern different information. A natural origin does not automatically mean untreated, and a laboratory origin does not mean the material is merely an imitation of its stated counterpart.
Arthur: A useful description should let you answer those questions without guessing from an appealing colour name. Ruby red might describe a shade, while laboratory-created ruby describes a particular material and origin. The extra words are doing important work. Jewellery can be romantic in its design while remaining admirably plain-spoken on its label.
Valera: Read the complete wording rather than one prominent phrase. A title, specification and care note should not leave contradictory impressions. If the stone is described only as created, crystal or simulated, ask what the exact material is. Those words do not necessarily supply the same information, and their meaning should not be assumed from context alone.
Arthur: Keep the questions proportionate to the purchase. A fashion accessory chosen for colour may need a straightforward, accurate material description. A costly purchase may justify more detailed documentation and independent assessment. In both cases, the basic principle is the same: understand what is being offered before deciding whether it is the piece you want.
What synthetic means in gemmology
Valera: GIA explains synthetic gems through their close chemical, structural and physical relationship to the natural counterpart. The distinction concerns origin: laboratory production instead of natural formation. This is why synthetic should not be used casually as a synonym for any decorative imitation. The actual material name remains essential to an accurate description.
Arthur: Think of the word as information, not a verdict about whether a piece is allowed to be beautiful. A buyer may prefer a natural origin, choose a laboratory-created counterpart or enjoy another clearly described material. The useful decision is an informed preference. An argument about which object deserves to look attractive is considerably less productive.
Valera: Laboratory-created versions exist for several gem materials, but the details vary. Do not assume every item sold as manufactured crystal is the synthetic counterpart of a named natural gem. Obtain the full description and any relevant treatment information. Some materials have particular compositional or structural details that broad marketing language does not explain.
Arthur: Nor should you assume that a perfectly even colour proves laboratory origin or that visible inclusions prove natural origin. Appearance can suggest questions, but it does not establish an answer. A convincing photograph is still a photograph, even when enlarged until the stone looks big enough to furnish a conservatory.
An imitation is a different material used for resemblance
Valera: GIA uses simulant for a material that looks like another gem but differs in its composition, structure or properties. Cubic zirconia used to resemble diamond is a familiar example. Laboratory-grown diamond is a different category: it is diamond of laboratory origin, rather than cubic zirconia with a more ambitious description.
Arthur: The intended comparison matters. A material can be described accurately in its own right and also be used to imitate another. The problem is not that someone enjoys a clear sparkling stone. The problem arises when the wording encourages them to believe they are buying a different material. An honest label leaves room for many perfectly enjoyable choices.
Valera: Glass can also imitate the appearance of various gems, and other manufactured or natural materials may be used as simulants. Ask what the piece actually contains rather than stopping at what it resembles. Different materials can have different durability and care needs, so identity remains useful after the purchase as well as during it.
Arthur: A well-described imitation does not need to apologise for being decorative. It should simply be sold for what it is. Jewellery chosen for style can be delightful without being promoted into a gem category it does not occupy. The label should not be the most theatrical part of the object.
Natural and untreated are not the same statement
Valera: Natural describes origin, while treatment concerns processes applied to a material. Ask about treatments and their implications when relevant to the piece. Do not infer that a natural gem has received no treatment, or that a laboratory-created gem requires no further questions. Clear disclosure helps you understand both expectations and appropriate care.
Arthur: This is why one reassuring word cannot carry the whole description. Natural may answer one question while leaving several others open. Likewise, created does not explain every detail about the material, setting or finish. Read the actual specifications and ask a focused question when something important remains unclear.
Valera: Treatment information can affect how a stone should be handled or cleaned. The complete jewellery also includes settings, adhesives, coatings and other components that may impose their own limits. Ask for care guidance for the actual piece rather than selecting a method solely because the main stone belongs to a familiar gem family.
Arthur: The objective is understanding, not suspicion about every purchase. Good questions allow the seller to explain the product accurately. If an answer remains vague, you can pause, choose another piece or obtain suitable independent advice. A deadline for a party does not make missing information more reliable.
Photographs cannot authenticate origin
Valera: Natural and laboratory-created counterparts can look very similar, and identification may require appropriate gemmological testing. A colour photograph cannot reliably establish origin, treatments or all aspects of identity. GIA’s work on laboratory-grown diamonds, for example, explains the role of specialised examination in distinguishing origin. Avoid accepting visual certainty where proper testing is needed.
Arthur: A phone torch, an online image comparison or a confident comment is not a substitute for an appropriate report. Nor is an unusually clear stone automatically laboratory-grown. The internet is very good at enlarging pictures and rather less consistent at accepting the limits of what those pictures can establish.
Valera: If the value or purpose of a purchase makes independent documentation important, ask what report is available, who issued it and which material it describes. Check that the document corresponds to the particular stone or item where applicable. A report concerning one stone does not automatically describe every stone in a piece of jewellery.
Arthur: Read what a document actually says rather than treating the word certificate as a complete explanation. A seller’s product card, a guarantee about workmanship and a gemmological identification report perform different roles. You may not need every form of documentation for a modest fashion purchase, but you should understand the information you are relying on.
Do not infer composition from a colour name
Valera: Product language sometimes uses gemstone names as colour references. If the wording is ambiguous, ask whether it names the actual material or describes a shade. Blue does not establish sapphire, and a ruby-like red does not establish ruby. Accurate descriptions should make the distinction understandable without requiring the customer to decode it from a photograph.
Arthur: The same care applies to crystal. The word can appear in several jewellery contexts and should not automatically be read as natural rock crystal, laboratory-created gemstone or a particular branded material. Ask for the exact composition being claimed. One attractive word should not be expected to fill an entire specification sheet.
Valera: Separate the stone description from the metal description too. A laboratory-created gemstone can appear in jewellery made from many different metals and finishes. Gold-coloured, gold-plated and solid gold are different statements. The identity of one component does not establish the composition of the others.
Arthur: A clear shopping note might therefore have separate entries for stone, origin, treatment information, metal, dimensions and fitting. It is not glamorous prose, but it makes comparison easier. Once the facts are understood, you can return to the much more enjoyable question of whether the design belongs in your wardrobe.
A glossary that keeps the questions separate
| Term | What it generally tells you | What to clarify |
|---|---|---|
| Natural gemstone | Natural origin of the stated material | Identity, relevant treatments and care |
| Laboratory-created or synthetic counterpart | Human-produced origin with the counterpart’s essential gem properties | Exact material and relevant details |
| Simulant or imitation | Resemblance to another material | What the simulant actually is |
| Treated | A process has affected the material | Treatment type and practical implications |
| Crystal | Context-dependent wording | Exact composition and intended meaning |
| Gemstone colour name | May identify material or merely a shade | Which claim the description is making |
Valera: Use the glossary to identify missing information, not to diagnose a stone yourself. A careful word can narrow the question, but it does not replace appropriate testing or a clear product specification. If a seller uses several terms interchangeably, ask them to describe the actual material in a single unambiguous sentence.
Arthur: That sentence should be more useful than “a beautiful stone of exceptional quality”. Beauty is a judgement you can make; identity is information the description should provide. Both can matter to a purchase, but they are doing different jobs.
Durability belongs to the material and the whole piece
Valera: Laboratory origin does not make every gemstone equally resistant to scratches, impact, heat or chemicals. Different materials have different properties, and hardness is only one part of durability. The setting, construction and any treatments also matter. Ask about suitable use and care for the particular piece rather than assuming manufactured means indestructible.
Arthur: A stone can be resistant to one kind of damage and still need sensible handling in another situation. The jewellery also contains a clasp, string, setting or coating that may be the limiting component. The most robust-sounding word in a listing does not grant the complete piece immunity from ordinary wear and accidents.
Valera: Follow guidance before using ultrasonic or steam cleaning, soaking or applying a chemical cleaner. Some materials, treatments and constructions are unsuitable for particular methods. If identity or care is unclear, ask the seller or a qualified jeweller. A gentle-looking machine is still a cleaning process with effects that should be understood.
Arthur: Store pieces so they do not rub unnecessarily against one another, and inspect visible damage or changed fittings before wear. A laboratory-created stone can have sentimental value just as any other jewellery can. Appropriate care protects the actual object rather than a story about how it ought to behave.
Compare price through complete, current offers
Valera: Compare actual products with their stated materials, dimensions, workmanship, settings and documentation. Do not assume that every laboratory-created item will have the same price relationship to every natural item. A loose stone and a finished piece of jewellery are different purchases, and the surrounding design can contribute substantially to the cost.
Arthur: Avoid treating a low price as proof of origin or a high price as proof of quality. Neither replaces accurate information. If two pieces are being compared, note what each includes. A necklace’s chain, metal, construction and finishing may differ even when the visible stones appear similar in separate photographs.
Valera: Jewellery bought for enjoyment should not be selected on an unsupported promise of future resale value. If resale or valuation is central to a substantial decision, obtain appropriate current independent advice rather than relying on a broad claim about natural or laboratory origin. This guide explains terminology and shopping questions, not an investment forecast.
Arthur: A practical budget can focus on what you want to wear and how often you expect to enjoy it. A beautiful, clearly described piece can be worthwhile without a prediction about its future price. It is allowed to be an accessory rather than a small portfolio wearing a clasp.
Environmental and ethical claims need specific evidence
Valera: Laboratory-created does not, by itself, answer every environmental or ethical question. Production, energy use, supply chains, metal sourcing and manufacturing conditions can differ. Look for specific, relevant evidence behind a claim rather than assuming a single origin label proves the complete piece has a particular impact.
Arthur: Ask what a statement covers. It may concern one material, one supplier or one production process rather than the entire finished necklace. A claim becomes more useful when its scope is clear. A leaf icon and an agreeable adjective cannot explain the whole journey of a piece of jewellery.
Valera: Be equally careful about sweeping claims concerning all natural materials or all laboratory production. Compare the information actually available for the purchase you are considering. If evidence is limited, acknowledge that limitation rather than replacing it with a confident generalisation. Honest uncertainty is preferable to a convenient story presented as a verified fact.
Arthur: You can still make a choice that fits your preferences. The aim is to know which parts of the decision are supported by information and which are personal priorities. An informed purchase does not require pretending that every supply-chain question has a simple universal answer.
Three shopping situations, three useful questions
Valera: First, imagine a blue pendant described only as crystal. If material identity matters to you, ask exactly what the blue component is and what the metal is. Do not infer that it is natural sapphire, laboratory-created sapphire or rock crystal. The first useful step is a clear description, not a visual guess.
Arthur: Second, imagine a gift listing that says laboratory-created ruby. Confirm the exact material description, relevant treatment information, dimensions and care, then check whether the recipient likes the design. Accurate origin information is useful, but it does not tell you whether the necklace is the right length or the earrings have a fitting they enjoy.
Valera: Third, imagine an expensive stone purchase where origin is central to the price and purpose. Ask about appropriate independent identification and verify what the report covers. Compare current offers using the complete specifications. Do not rely on a photograph, a verbal assurance without detail or a document that cannot be connected to the actual item.
Arthur: These situations require different levels of investigation, but the starting question stays wonderfully plain: what am I buying? Once answered, the shopper can decide whether it meets the intended role. The vocabulary should make that easier, not provide an elegant way to avoid saying what the object contains.
Make a gift’s meaning and materials equally clear
Valera: If origin is important to the recipient, discuss it before buying rather than assuming a preference. Some people value natural formation, others enjoy a laboratory-created counterpart and others mainly care about design. There is no reliable way to infer that preference from age or the importance of the occasion. A focused question can prevent an avoidable disappointment.
Arthur: Do not attach a symbolic story that contradicts the material. You can choose a colour associated with a birthday without claiming the piece contains a particular natural birthstone. Explain the intended association and the actual composition separately. A thoughtful gift is more convincing when its factual description is as honest as its personal message.
Valera: Include care and purchase information where useful. Confirm fit, fastening, delivery and return conditions for the specific item, especially personalised or altered pieces. A well-described stone is one part of a useful gift; the complete jewellery still needs to be something the recipient can comfortably wear and look after.
Arthur: Then allow them to enjoy it for what it is. Laboratory-created, natural and clearly described imitation materials can each appear in attractive jewellery. The important distinction is an informed choice rather than a surprise hidden in ambiguous wording.
Frequently asked questions
Are lab-created gemstones the same as imitation stones?
Valera: No. A synthetic counterpart has essentially the same chemical composition, crystal structure and properties as the corresponding natural gem, while differing in origin. A simulant resembles another stone but is a different material. Ask for the exact material name and origin rather than treating all manufactured jewellery stones as one category.
Is laboratory-grown diamond the same as cubic zirconia?
Arthur: No. Laboratory-grown diamond is diamond of laboratory origin. Cubic zirconia is a different material that can be used to resemble diamond. Both need accurate descriptions. Their similar visual role in some jewellery does not make the material names interchangeable.
Can I identify a lab-created gemstone from a photograph?
Valera: A photograph cannot reliably establish origin or all aspects of identity and treatment. Natural and synthetic counterparts can look similar, and appropriate gemmological testing may be needed. For a purchase where identification matters significantly, ask about suitable independent documentation rather than relying on visual certainty.
Does natural mean untreated?
Arthur: No. Natural concerns origin, while treatment is a separate question. Ask about relevant treatments and their implications for the actual piece. Do not assume a laboratory-created material needs no further information either. Accurate description and appropriate care should cover the jewellery as a whole.
Are all lab-created gemstones easy to care for?
Valera: No. Care depends on the material, treatments, setting and other components. Laboratory origin does not make every piece equally resistant to impact, heat, moisture or cleaning processes. Follow instructions for the complete jewellery and ask before soaking or using a cleaning machine if suitability is unclear.
Does lab-created automatically mean environmentally preferable?
Arthur: The origin label alone does not establish the complete environmental impact. Look for specific evidence about the relevant production and supply chain, and check what the claim covers. Avoid assuming that every laboratory process or every finished piece has the same impact.
Choose with clear terms and realistic expectations
Valera: Lab-created gemstone jewellery is easier to assess when identity, origin, treatment, metal and construction are described separately. Confirm the facts that matter to your purchase, obtain appropriate documentation where needed and follow care guidance for the whole piece. Appearance can inspire a choice, while accurate information supports it.
Arthur: Explore necklaces, earrings and bracelets by design, then read each description carefully. Choose something you enjoy for what it actually is. A lovely stone should not need its label to wear a disguise.
