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
Ammolite is a rare gemstone of organic origin that is fairly new to the market, with commercial mining beginning only in 1981. Ammolite is the fossilized shell of ammonites, which are composed primarily of aragonite, the same mineral that makes up nacreous pearls. Ammolite's main attraction is a remarkably vivid play of color. Ammolite is typically used to create doublets or triplets that are suitable for making durable jewelry.
I have not made a lot of purchases from GemSelect, but have been very satisfied with those that I have. The quality of the gems has been good, and I like the pictures provided of the actual gemstones being reviewed. I will certainly be back for more at another time.
