How to tell genuine Baltic amber
Genuine Baltic amber is fossilized tree resin. Appearance and simple home tests cannot, on their own, establish that a piece is Baltic amber or identify every treatment. Before buying, ask about the material, origin and processing category; for a valuable or disputed piece, seek professional identification.
What to ask the seller
Ask whether the material is amber rather than an imitation, where it comes from, and whether it is natural, modified, reconstructed (pressed) or bonded. Ask separately about the metal, bead size and total weight. “Genuine” should not be treated as a promise that a piece is untreated or made from one unjoined piece of amber.
Natural, treated and pressed amber
The International Amber Association distinguishes processing categories for Baltic amber:
- Natural: shaped and finished mechanically, without other modification.
- Treated (also described as modified): amber changed by treatment, such as heat, pressure, dyeing or other processes.
- Reconstructed (pressed): amber pieces joined under heat and pressure.
- Bonded: amber parts joined with a binding agent.
These terms describe processing, not just appearance. Pressed amber contains amber material; it should be described clearly rather than presented as an unmodified single piece. Plastic imitation is a different material.
What do home tests tell you?
Salt water
A float test can be a clue about density, but some substitutes also float. Metal fittings, string and other components affect the result. Do not immerse assembled jewelry in salt water: it can affect its other materials. Floating does not prove Baltic origin or processing category.
UV light
Fluorescence can help an examiner, but its appearance varies with the material, treatment and light source. A glow is not proof of authenticity, origin or lack of treatment. Do not look directly into a UV light.
Static electricity
Attracting tiny paper pieces after rubbing is not a reliable identification result: other materials can build static too. Rubbing can also mark a soft surface. Do not use this as your deciding test.
Smell, heat and solvents
Smell is subjective. Do not burn, heat, scratch or apply solvents to jewelry to try to identify it. Those methods can damage the piece and do not replace professional examination.
What do amber colors mean?
Cognac describes warm brown tones; cherry deeper red-brown; lemon pale yellow; and milky a cloudy, opaque appearance. Green amber also appears in our range. Color names describe appearance, not proof of Baltic origin or an untreated material.
Blue amber can show a blue optical effect in particular lighting. A product called “blue amber” is not automatically Baltic or Dominican amber. Ask for the selected piece’s origin, processing and appearance in daylight. You can compare our blue faceted oval stone, then ask about the details of that item.

Authenticity questions
Can I prove amber is genuine at home?
Home observations can offer clues, but none of the tests here reliably establishes every material, treatment and origin. Use seller disclosures and professional identification when you need a dependable conclusion.
Is pressed amber the same as plastic?
No. Reconstructed or pressed amber is made from amber material joined under heat and pressure. Plastic imitation is a different material. The processing category should be stated clearly.
Does green or blue mean the amber is Caribbean?
No. Color alone cannot establish a piece’s geographic origin. Check the individual record and ask if its origin is unclear.
