Malachite a Stone of Transformation

Malachite is a copper carbonate hydroxide mineral that is very closely related to azurite, and both share nearly the same chemical composition. While azurite is blue, malachite is green, and it is slowly formed when the azurite reacts with oxygen in the air and “weathers”, leaving a more “stable” mineral behind.

Azurite the Stunning Blue Gemstone

Azurite is one of the most intensely colored blue gemstones in the mineral kingdom, and has been renowned since antiquity. It is a carbonate mineral with a rather complex chemical formula, and is closely related to another mineral, malachite (combinations of both azurite and malachite are called azurite-malachite). In fact, azurite weathers into malachite during a process which changes its carbonate to hydroxide ratio from 1:1 to 1:2.

The Properties of Peridot

Peridot is the gemstone variety of the mineral olivine and a popular stone for jewelry, due to its beautiful olive-green color. Non gemstone varieties of olivine have been found in reddish or brownish shades as well, but the name “peridot” has come to be associated with only the gemstone grade olive-green specimens.

The Properties of Garnet

Garnet is a well-known gemstone that actually comprises several varieties of similar minerals that go by different names and colors but are all collectively known as “garnet”. Names like almandine, andradite, grossular, pyrope, and spessartine might not sound familiar, but they are all just different kinds of garnet. The hardness ranges from 6.5 to 7.5 on the Mohs scale, so garnet is a pretty hard gemstone, no matter what the variety. In fact, the harder varieties of garnet are being used as abrasive material in some industries. The color of garnet differs depending on what type of garnet it is.
