Treatment Back To Top
Assembled gemstones have gone through a type of layering treatment used to enhance color and durability. Assembled stones typically come in the form of doublets and triplets. The treatment is very common for ammolite and opal. It is very well accepted within the gem trade, as long as the treatment is disclosed. Assembled stones are typically composed of a host or matrix rock layered with a thin strip of precious stone. The host rock backing provides thickness, strength and overall durability. More about treatments
About Opal Doublet
More than any other gem, each opal is distinctly an individual. No other stone has as rich and varied a folklore. Opals are also the most delicate gems commonly worn. They require special care to insure their health and longevity.

Opal's fire was long thought to be the result of iridescence. However, with the advent of scanning electron microscopes, we now know that it is a result of diffraction.

Opal is relatively soft, with a rating of 5.5-6.5 on Mohs Scale. Despite its frequent use in rings, opal is a poor choice for a ring stone; it is much better suited to earrings, pins, and pendants.

Major suppliers include Australia, Brazil, Mexico, and the US. Values are normally determined by the presence and nature of color flashes.

An opal doublet consists of a slice of opal glued to a black backing, designed to imitate the appearance of a solid black opal. Adhering the slice of opal to a black backing causes the colour to become much darker and more vibrant. Opal doublets are highly regarded as an inexpensive alternative to solid opals which are very expensive in larger sizes.
