The Amber Buying Checklist: 12 Questions to Ask Every Seller

Amber is one of the few collectables where almost everything that matters is invisible. Two stones can sit side by side on a dealer's table, look near-identical in a photograph, and differ completely in age, origin and how much heat and dye they have been through. Since most of us now buy from images rather than in person, the gap between a lovely piece and an expensive mistake usually comes down to a handful of questions asked before any money changes hands.

What follows is the checklist worth keeping on your phone. Ask all twelve on a serious purchase; ask the first six even on a modest bead. A knowledgeable seller will be pleased you asked. A vague one will start to look vague.

Origin, Age and Species

Start with geography. Where a piece came from shapes its colour, its fluorescence and its price, and it is the first thing a careless or dishonest seller will hand-wave.

1. Where exactly was this found? "Baltic" covers a lot of ground, though the classic succinite comes from the Sambia peninsula. Dominican amber hails from the Caribbean and often shows a strong blue fluorescence. Burmese amber from Myanmar is prized for its inclusions but raises real ethical and import questions, so satisfy yourself on that front. Mexican amber from Chiapas and Romanian rumanite are their own distinct materials. "Europe, somewhere" is not an answer.

2. How do you know it's amber and not copal? Copal is far younger resin, softer, sometimes faintly tacky, and it reacts to solvents that leave true amber alone. Some copal is sold as amber in good faith; some is not. Ask how the seller reached their conclusion. "It's definitely amber" with no reasoning is not a test.

3. Does it have any history? An old collection label, a previous dealer's invoice, a note of the mine or region. This is unnecessary for a small cabochon, but on a serious specimen the paper trail is part of what you are buying.

Treatment, Enhancement and Reconstruction

Treating amber is normal and entirely legal. Describing a treated piece as untouched is where the trouble starts, so ask plainly and listen for a straight answer.

4. Has it been heated, clarified or "cooked"? Baltic amber is routinely warmed to clear cloudy material or to create the glittering "sun spangles" some collectors love. Dominican amber is often heated to bring out blue and green tones. Heat-treated amber is still genuine amber, but it belongs to a different part of the market from untreated material and should be priced accordingly.

5. Has it been dyed, filled or coated? Look out for resin filling cracks, dye used to imitate deep cognac or cherry-red, and lacquer or oil on the surface. A loupe held to a bead's drill hole often reveals dye gathering in the threads, which is a useful tell.

6. Is this one solid piece, or pressed amber? Pressed amber — ambroid — is made from offcuts and dust fused under heat and pressure. It is common in beads and inexpensive carvings. Expect a cloudy, swirling internal flow and an unusually flat, even glow under ultraviolet.

Weight, Size and Inclusions

7. What is the exact weight in grams? Ask for the number, not "large" or "chunky", and ask whether that is the stone alone or including the mount. Weight drives amber prices more than any other single factor, and bigger pieces command disproportionately more, so this is not a detail to skip.

8. What are the dimensions, and what condition is it in? Request measurements in millimetres, both across and deep, and ask about chips, crazing, filled cracks or any restored edges. A polished surface and a natural one are different things; know which you are being offered.

9. Are there inclusions, and are they natural to the piece? Insects and plant matter are why many people collect amber at all. Modern flies set into resin are an old trick, and genuine inclusions can also be inserted into a bored channel. Under a lens, a natural inclusion sits inside the resin with a faint halo, and there should be no seam or drilled passage leading to it. A large, perfectly centred insect in a flawless, perfectly clear block deserves extra questions and a second opinion.

Evidence, Returns and Your Rights

10. Will the details go in writing on the invoice? Ask for origin, weight, treatment and whether the piece is solid or pressed to be stated on the invoice or receipt. A listing description can be edited later; an invoice is harder to argue with.

11. What is your return policy, and how long do I have? Online purchases in the UK generally carry a short cancellation window — commonly around fourteen days, though the details depend on the order, so check the terms before you buy. Ask who pays return postage, and send anything valuable by tracked, insured post. If a purchase goes seriously wrong, take proper consumer advice.

12. Can I see more — daylight photographs, a shot under UV, and a proper look before I pay? Request unedited images in indirect daylight, both sides, with a coin or ruler for scale. Ask for a picture under an ultraviolet torch: the glow varies by deposit and is one of the few clues that survives a photograph. If you can handle the piece, bring a loupe. A float test in very salty water will sink glass and many plastics, but copal floats too, so it proves very little about age.

How to Ask Without Ruffling Feathers
