How Much Is Amber Worth?
Fossilised tree resin, forty million years old, and the most convincingly faked gem on the market. Also, quietly, one with a serious sourcing problem.
Amber is not a mineral. It is the fossilised resin of ancient conifers and other trees, polymerised and hardened over tens of millions of years. It is extraordinarily light, warm to the touch, soft (2–2.5 on the Mohs scale) and it floats in saturated salt water. It also, uniquely among gems, sometimes contains the preserved body of something that was alive when dinosaurs were.
What drives the price: what is inside it
For plain amber, the drivers are ordinary: clarity, colour, size. Deep cognac and cherry tones are popular; the rare natural blue amber of the Dominican Republic and green amber command premiums.
But the real value in amber is inclusions. A clearly visible, complete, well-positioned insect can multiply the price by a hundred. A vertebrate — a lizard, a feather, a hatchling — belongs in a museum and prices accordingly. The gap between a plain bead and a scientifically significant inclusion is one of the largest in this entire site.
Typical fair prices
| Type | Fair price | Notes |
|---|---|---|
| Copal (young resin) | $1–$10 | Thousands, not millions, of years old. Not amber |
| Plain Baltic amber | $5–$50 | Beads, cabochons, small pieces |
| Fine cognac / cherry, larger | $50–$300 | Clarity and size drive it |
| Clear insect inclusion | $200–$2,000 | Complete, well-placed, identifiable |
| Rare inclusion / Dominican blue | $2,000–$10,000+ | Vertebrates, flowers, scientific pieces |
Fakes: amber is the easiest gem in the world to counterfeit
Because amber is soft, light and warm, and because the desirable feature is something suspended inside it, imitations are trivially easy to make. Modern resin with a shop-bought fly in it fools most buyers. Four tests, in ascending order of destructiveness:
The salt-water float. Dissolve enough salt in water and real amber floats; most plastics and glass sink. Copal also floats, so this test separates amber and copal together from plastic, not amber from copal.
UV light. Baltic amber fluoresces a distinct pale blue under longwave UV. Most plastics do not.
The acetone test. A drop of acetone on a discreet spot leaves real amber unmarked. Copal becomes tacky within seconds. Plastic often does too.
The hot needle. Destructive, and a last resort. Amber smells of pine resin and incense; plastic smells acrid and chemical; copal smells sweet and softens.
And look at the insect. Genuine inclusions are usually distorted, incomplete, surrounded by fine bubbles and flow lines, often with the legs splayed in a struggle. A perfect, centred, museum-posed specimen in flawless clear resin is a fake, every time.
Burmese amber: the part the trade does not discuss
This deserves plain speaking. Burmese amber — burmite, roughly 99 million years old, from Kachin State, Myanmar — is the single most scientifically important amber on earth. For several groups of Cretaceous organisms it is essentially the only source of well-preserved specimens.
It is also mined in an active conflict zone. Researchers and human-rights bodies have documented that the amber trade there has generated revenue for armed actors, alongside reports of forced labour, displacement and fatal mine collapses. In 2020 the Society of Vertebrate Paleontology called for a moratorium on publishing research on Myanmar amber acquired after the military took control of the mines. The palaeontological community remains divided; journal policies have tightened; and a further finding, that only a tiny handful of the several hundred Burmese amber papers included any Myanmar-based co-author, has drawn a second criticism about extractive science.
A buyer cannot verify the provenance of a piece of burmite. If that matters to you — and we think it reasonably might — Baltic and Dominican amber are abundant, beautiful and carry no comparable problem.
Inclusions must be photographed backlit, at magnification, and from more than one angle. Our sister site keeps a photographed amber collection shot that way.
Watch-outs
- Copal sold as amber. Copal is resin that has not finished fossilising — often only a few hundred or thousand years old. It looks identical and is worth a fraction. The acetone test separates them.
- Plastic with a modern insect. Suspiciously perfect specimens in flawless resin. Real inclusions are messy.
- Pressed or reconstituted amber (ambroid). Small fragments heat-fused under pressure. Legitimate if disclosed; look for flow lines and a “sun spangle” pattern of internal discs.
- Heat-treated amber. Clarified and darkened by heating. Standard and acceptable if declared. The disc-shaped “sun spangles” are a sign.
- Burmite of unverifiable origin. See above. There is no chain-of-custody scheme.
- Amber teething necklaces. Sold with health claims. There is no evidence of any analgesic effect, and paediatric bodies warn of strangulation and choking risk. Do not put one on a baby.
The International Gem Society covers amber testing and the copal distinction. Science and Communications Biology report on the ethics, law and politics of Myanmar amber.
Baltic amber, honestly labelled
Ask for the origin, ask whether it is pressed or heat-treated, and treat any perfect insect with suspicion. Baltic and Dominican amber are plentiful and untroubled.

How can I tell real amber from plastic?
Real amber floats in saturated salt water, fluoresces pale blue under longwave UV, and resists a drop of acetone. Plastic usually sinks, does not fluoresce, and may go tacky. A hot needle makes amber smell of pine resin, plastic of chemicals — but it damages the piece.
What is copal?
Tree resin that has not fully fossilised, typically thousands rather than millions of years old. It looks like amber, is worth a fraction, and is very often sold as amber. Acetone makes it tacky; amber is unaffected.
Why is amber with an insect so expensive?
Because a complete, clearly visible, identifiable inclusion is rare, and because it is a piece of preserved biology. Prices rise steeply from insects to spiders to vertebrates, and scientifically significant pieces reach museum figures.
Is Burmese amber ethical to buy?
Its provenance cannot currently be verified. Burmese amber comes from a conflict zone in Kachin State, and researchers have documented that the trade has funded armed actors. A palaeontological moratorium on newly acquired material has been called for. Baltic and Dominican amber carry no comparable issue.
Do amber teething necklaces work?
No. There is no evidence that amber relieves teething pain, and paediatric bodies warn about strangulation and choking. Do not use them.
Does amber hold its value?
Plain amber does not; it is inexpensive and abundant. Exceptional inclusions can appreciate, but that is a collector and scientific market with its own rules.
