Amber is fossilized tree resin, tens of millions of years old — warm to the touch, featherlight (it even floats in salt water) and glowing in honey, cognac and butterscotch tones. The most fascinating pieces hold ancient plant fragments or insects, tiny time capsules from prehistoric forests. Baltic and Burmese deposits are the most celebrated.GEMIC Institute tests every amber piece for authenticity in our Siem Reap laboratory — a crucial safeguard in a market full of imitations — and certifies it accordingly. Each specimen is unique; worldwide tracked shipping and a 30-day return apply.
