After storms, small sun stones are washed ashore by the sea. The observant ones can find them.
However, you should be careful not to confuse amber with the flammable phosphorus, which is sometimes washed out on the Bernāti beach. It is recommended not to put the pieces in the pockets and not to hold them for a long time in hands, but it is better to put them in some container, until you are sure that they do not ignite in the heat.
The Greeks called amber electron or “solar matter”. The Romans considered it as valuable as gold. The stone is at least 40 million years old. Composition: carbon 67–81 %, hydrogen 8,5-11 %, oxygen around 15 %, sulphur 0,46 %.
Amber, or sun stone, is a hardened resin that has generously dripped from pines grown in the forest and it is washed to the shore for thousands of years. The most generous sea for amber is from the Kurzeme coast of Latvia to the Polish border, but the richest place with both sea and land amber is the Sembia Peninsula in the Kaliningrad region, where the Yantarnaya deposits produce about 90 % of all the amber harvest in the world (about 700 tons annually).
