Real Baltic amber is a fossilised tree resin tens of millions of years old — warm, light, and full of natural character. Because it is prized and valuable, it is also widely imitated with copal, plastic, and glass. The good news is that genuine amber behaves in ways that fakes cannot easily copy. This guide walks through seven simple, mostly non-destructive tests you can do at home, explains the red flags to watch for when buying, and shows how a certificate of authenticity gives you the certainty that no single test can.

Why Amber Authenticity Matters
Genuine Baltic amber, known to scientists as succinite, is fossilised conifer resin that formed around the Baltic region roughly 40 million years ago. Its value comes from that great age, its warm natural color, and the tiny inclusions of ancient air and plant matter locked inside. An imitation may look similar at a glance, but it carries none of that history — and often a fraction of the value.
The market is full of look-alikes. Some are honest substitutes clearly labelled as resin or reconstituted amber; others are sold as the real thing at real-amber prices. Learning to tell the difference protects both your money and your trust in what you wear. The tests below are the same principles gemologists rely on, simplified for home use. Use two or three together — no single test is proof on its own, but a piece that passes several with flying colors is almost certainly genuine amber.
What Fake Amber Is Usually Made Of
Before testing, it helps to know what you are testing against. Most amber imitations fall into four groups, and each behaves differently.
- Copal — young, immature resin that has not fully fossilised. It looks remarkably like amber and even floats in salt water, but it is far softer, has a lower melting point, and dissolves more easily in solvents. Copal is the trickiest imitation because it is genuine resin, just millions of years too young.
- Plastic — bakelite, celluloid, acrylic, and modern polyester resins are moulded to mimic amber. They often feel subtly heavier or harder, may smell of chemicals or burnt plastic when heated, and rarely show convincing natural inclusions.
- Glass — heavy, cold to the touch, and impossible to scratch with a fingernail. Glass does not build a static charge and sinks immediately in salt water, making it one of the easiest fakes to spot.
- Pressed or reconstituted amber — real amber fragments melted and compressed into a single block. It is technically amber, but far less valuable than one natural piece, and often shows cloudy flow lines or an unnaturally uniform color.
The 7 Tests: How to Tell If Amber Is Real
1. The Salt Water Test
This is the classic and most reliable non-destructive test. Dissolve about two tablespoons of salt in a cup of warm water, stirring until no more salt dissolves. Gently drop your amber in. Because genuine Baltic amber is only slightly denser than saturated salt water, it floats or hovers just below the surface. Plastics and glass are denser and sink. The one caveat: copal floats too, so a floating piece still needs the warmth and static checks to be confirmed. Rinse and dry the piece afterwards, especially if it is set in silver.
2. The Warmth & Touch Test
Amber is an organic material and a poor conductor of heat, so it warms quickly against your skin and never feels cold and heavy the way glass does. Hold the piece in your closed hand for a minute. Real amber feels warm and light, almost weightless for its size. Glass stays cool and feels dense; many plastics warm up but feel harder and less alive. This test costs nothing and is a good first impression before you set up the salt water.
3. The Static Electricity Test
The ancient Greeks called amber elektron because of this very property — it is the root of the word electricity. Rub the amber briskly against a piece of wool, cotton, or your hair for around 30 seconds, then hold it close to a few small torn scraps of paper or a little dust. Genuine amber builds a static charge and attracts the light material. Most plastics generate weaker static and glass generates almost none, so a strong pull is a good sign of authenticity.
4. The UV Light Test
Under a UV or blacklight, genuine Baltic amber fluoresces — it typically glows a pale blue or milky blue-green, especially on an uncut surface. Copal shows a much weaker glow, and most plastics either stay dull or fluoresce a flat white. A small UV torch is inexpensive and makes this one of the more telling checks, though results vary with the amber's color and finish, so read it alongside the other tests rather than on its own.
5. The Inclusions & Look Test
Hold the piece to the light and look closely, ideally with a loupe or magnifier. Natural amber often contains tiny bubbles, plant fragments, cracks, or subtle variations in color. These small imperfections are a hallmark of the real thing. Imitations, by contrast, tend to look too perfect — flawlessly clear, uniformly colored, or dotted with suspiciously large, dramatic "insects" placed to impress. Perfectly identical beads across an entire strand are a warning sign of moulded plastic or pressed amber.
6. The Scratch & Hardness Test
Amber is soft but not as soft as copal or many plastics. Pressed gently, a fingernail will not scratch genuine amber, while immature copal may mark more easily. This test is more useful for what it rules out than what it confirms, and it should be done cautiously on an inconspicuous spot — the goal is a light press, never a gouge that would damage a finished piece.
7. The Hot Needle & Smell Test
This is the one destructive test, so use it only on raw material or where a tiny mark will not matter — never on a finished piece of jewelry. A needle heated and touched to the surface makes genuine amber release a faint piney, resinous scent. Copal smells sweeter and softens quickly. Plastic gives off a sharp, acrid chemical smell of burning synthetic. Because it leaves a mark, most people skip this test on jewelry and rely on the six non-destructive checks above.
Real vs Fake Amber at a Glance
| Test | Genuine Baltic Amber | Common Fakes |
|---|---|---|
| Salt water | Floats or hovers | Plastic & glass sink |
| Warmth | Warms fast, feels light | Glass stays cold & heavy |
| Static | Strong charge, attracts paper | Weak or no charge |
| UV light | Blue / blue-green glow | Dull or flat white |
| Inclusions | Natural bubbles, variation | Too perfect or fake insects |
| Smell (hot needle) | Piney resin scent | Acrid chemical / burnt plastic |
Red Flags When Buying Amber
Tests are useful once a piece is in your hands, but many problems can be spotted before you buy. Watch for these warning signs.
- A price too good to be true. Genuine natural amber cut and set by hand is not a bargain-bin material. Very cheap "amber" beads are usually plastic, copal, or pressed amber.
- Flawless, identical pieces. A whole strand of beads matched perfectly in color and clarity is a strong sign of moulding rather than natural stone.
- Dramatic, oversized insects. Genuine inclusions are usually small and subtle; large, showy creatures perfectly centered in clear resin are often planted in plastic.
- Vague sourcing. A seller who cannot say where the amber comes from, or who avoids the words "natural" and "Baltic," should give you pause.
- No certificate. Reputable sellers provide a certificate of authenticity confirming natural Baltic origin. Its absence is the biggest red flag of all.
How AMBERRA Guarantees Genuine Amber
At AMBERRA, every piece is made with natural Baltic amber set by hand in 925 sterling silver by artisans in Ubud, Bali. Because the amber is genuine and never pressed, dyed, or reconstituted, each stone is one of a kind, with its own color and inclusions — exactly the natural variation the tests above are designed to detect.
Every order arrives with a certificate of authenticity confirming the natural Baltic origin of the amber, so you never have to rely on a home test alone. If you would like to see the natural spectrum of genuine amber, our guide to amber colors shows the full range, and our article on genuine Baltic amber goes deeper into sourcing and craftsmanship. To understand the cultural side of the stone, the meaning of Baltic amber explores its history and symbolism.
