Copal

In recent years, some jewelry manufacturers have given the name “Caribbean Amber” to an industrially produced green gemstone made from hardened young tree resin, often copal from Colombia.Copal from Colombia is sometimes only a few hundred years old and therefore relatively soft (Mohs 1 – 1.5). But the desired appearance is that of old, transparent green Dominican amber.

The hardened copal lumps are made transparent by placing so-called water settlers in the autoclave. The green color is obtained by adding water at each stage of the process. After the copal has hardened, the aluminum foil is removed and the hardened resin is cut to produce the desired shape (i.e. bead or cabochon). It is then mixed with talcum and heated again in the autoclave. Thereafter, it can be cut and polished to obtain the desired finish.
