The amber which was known to our ancestor - and is still common in the jewel market of our times - is that originating from almost all countries of the Baltic Sea, especially Poland, Lithuania and the great deposit of Kaliningrad (Russia). This kind of amber, dating back to about forty million years, is the fossil resin of great conifers. Being originally a very thick and air-bubbled rosin, it often looks opaque, ranging in colour from white to light yellow. It is rarely found in an orange colour.
