Mosaic Opal Triplet Gemstone & Information | Gemopedia by JTV | Gemopedia™
As an affordable alternative to larger sized solid opals, mosaic opal triplets provide an affordable, and stylish, substitute. They are created by assembling a montage of small, thin opal slices and adhering them to a solid base material, which may be natural or man-made. The base material, often dark in color, provides a dramatic backdrop to the overall appearance of the triplet.
