A real chunk of certified Baltic amber with a large, perfectly visible insect inclusion, set in a 100% copper ring.
Amber is formed from resin exuded from tree bark, although it is also produced in the heartwood. Resin protects trees by blocking gaps in the bark. Once deposited, the resin chemically matures into intermediate forms called copals and finally into amber after millions of years. The amberization process is estimated to take between 2 and 10 million years.
This ring is a US size 7.
