It is sometimes used to imitate other, more opals.An opal doublet uses a thin slice of opal for the top portion of the stone.natural opal is fused to a black stone backing.
The color of the opal used in the doublet is all that is seen...If seen in reflected light, a separation line may be seen. In the case of opal doublets, a backing layer of onyx or matrix (ironstone) gives the more fragile opal layer support and can make the opal look darker and higher quality
