An opal triplet is made up of 3 parts. A thin, sparkling slice of opal is placed on either black onyx, obsidian or black opal potch. A dome of crystal or quartz is placed on the top for protection and amplification of color. It is the last element that I enjoy the most. While triplets can be considered lesser in value than a doublet because of the opal content, I find it to be more jewelry-ready due to the vibrancy as a whole.
These opal triplets are graded A-C, Measurements +/- .3mm
