What is spinel gemstone

Spinel is the great impostor of gemstone history: many famous rubies in crown jewels around the world are actually spinels. The most famous is the Black Prince's ruby, a magnificent 170-carat red spinel that now adorns the Imperial State Crown of England in the British Crown Jewels after a long history: Henry V even wore it on his battle helmet!

Peridot belongs to the forsterite-fayalite mineral series, which is part of the olivine group. It is one of the few "idiochromatic" gems, meaning its color comes from the basic chemical composition of the mineral itself, not from minor impurities, and therefore will only be found in shades of green.

Opals stand in a class by themselves. More than any other gem, each opal is distinctly an individual. No other stone has as rich and varied folklore. They are both one of the luckiest and unluckiest gems a person can own.

Morganite for engagement rings
Morganite is a beryl, colored by traces of manganese. Although violet and peach are possible colors, the most common and preferred color is pink. Heat and light will remove the yellow component from peach beryl, so it is often heated to get "pinker" stones.

Moonstone or "Adularia," an orthoclase feldspar, was initially named for an early mining site at Mt. Adular in Switzerland. From this tradition, we derive the term "adularescence," which is the optical phenomenon of iridescence, which creates a billowy, floating blue to white light in this gem.

Where malachite is found
Malachite is rarely enhanced, although lower quality, less compact pieces may be stabilized with plastic resins or given a surface polish with wax. Although synthetic malachite has been manufactured for research purposes, it has not been found in the gem marketplace.

Kunzite is a variety of spodumene, which is a fairly common mineral, but the clear, pale pink to lilac ( and sometimes blue, green, or yellow) colored form of it is much rarer to come by. It was first found in California in 1902, and is named after the famous mineralogist George F. Kunz who first identified it.
