Garnets are a group of silicate minerals that have been used since the Bronze Age as gemstones and abrasives. All species of garnets possess similar physical properties and crystal forms but differ in chemical composition. The different species are Pyrope, Almandine, Umba River, Spessartine, Grossular, Uvarovite and Andradite. Garnet is 6.5 – 7.5 on the Mohs hardness scale.

Tanzanite, another December Birthstone is the blue and violet variety of the mineral zoisite, from Tanzania. It has a hardness of 6.5 on the Mohs scale. Tanzanite is noted for its trichroism, appearing alternately blue, violet and burgundy depending on crystal orientation. Blues appear more evident in fluorescent light and violet hues can be seen under incandescent light. In its rough state tanzanite is colored a reddish-brown to clear, and it requires heat treatment to remove the brownish veil and bring out the blue-violet of the stone.
The gemstone was given the name “tanzanite” by Tiffany & Co. after Tanzanite, the country in which it was discovered. In 2002, the American Gem Trade Association chose tanzanite as a December birthstone.
Zircon is one of December’s birthstones. It is a colorful gem with high refraction and fire that’s unfairly confused with cubic zirconia.

Its hardness is 7.5 on the Mohs scale.

Topaz is the birthstone for November. Most Topaz crystals are colorless, however topaz crystals that are sold in jewelry stores are pink, sherry brown, or yellow, blue, gray, green, reddish pink. It’s hardness is 8 on the Mohs scale. Topaz in its natural state is a golden brown to yellow, a characteristic which means it is sometimes confused with the less valuable gemstone citrine. A variety of impurities and treatments may make topaz wine red, pale gray, reddish-orange, pale green, or pink, and opaque to translucent/transparent.
Orange topaz, also known as precious topaz, is the traditional November birthstone, the symbol of friendship, and the state gemstone of the Utah.
Imperial topaz is yellow, pink, or pink-orange. Brazilian imperial topaz can often have a bright yellow to deep golden brown hue, sometimes even violet. Many brown topazes are treated to make them bright yellow, gold, pink, or violet colored.
Blue topaz is the state gemstone of the Texas. Naturally occurring blue topaz is quite rare. Typically, colorless, gray or pale yellow and blue material is heat treated and irradiated to produce a more desired darker blue.
Tourmaline comes in a variety of colors. Usually, iron-rich tourmalines are black to bluish-black to deep brown, while magnesium-rich varieties are brown to yellow, and lithium-rich tourmalines are almost any color: blue, green, red, yellow, pink, etc. Rarely, it is colorless. Bi-colored and multicolored crystals are common, reflecting variations of fluid chemistry during crystallization. Crystals may be green at one end and pink at the other, or green on the outside and pink inside; this type is called watermelon tourmaline. Some forms of tourmaline are dichroic in that they change color when viewed from different directions.
The opal is a hydrated amorphous form of silica. As such, its water content may range from 3 to 21% by weight, but is usually between 6 and 10%.

Black opals are the rarest, white and greens are the most common. Opal is the national gemsotne of Australia.
