Physical Qualities of Ametrine Ametrine is a mix of both amethyst and citrine, and can be either natural, or artificially manufactured through heat treatment. Virtually all naturally occurring ametrine is found in Bolivia, hence it is sometimes known as bolivianite. It occurs in either typical quartz crystal form, or in massive form. The colors of both purple and yellow/orange are distinctly separated in their individual zones within ametrine; the difference is due to the iron ions within experiencing different zones of radiation exposure during the formative process. Like quartz, ametrine has a Mohs hardness of 7. The color banding differences

The versatile calcite
Calcite (CaCo3) is a highly versatile crystal that comes in many types of colors and crystallized forms. It is too soft to be actually used as jewelry for the long term, having only a hardness of 3 on the Mohs scale. Its color ranges from colorless to orange, red, blue, green, down to black. Calcite is common, and occurs worldwide. It is found as masses, microcrystalline crystals, concretions, fibrous, and singular crystals (scalenohedrons and rhombohedrons). It is also soluble in hydrochloric acid, and can be burned in high flame, breaking down into carbon dioxide and lime in the process. Some

The exclusive Tanzanite
Tanzanite is the name given to the blue or purple variety of zoisite found only in Tanzania. Zoisite is a mineral of above average hardness, about 6.5 on the Mohs scale, and appears in a range of colors, such as blue, green, brown, pink, and colorless. In Tanzania, tanzanite is mined in the Merelani Hills. The rarity and exclusiveness of tanzanite might seem like an exaggeration, but only Tanzania produces blue zoisite of such quality. Now, it must be remembered that any blue or purple colored zoisite could be called tanzanite, although it may never have originated from Tanzania, just
