Perfect for any kind of jewelry purpose. All tanzanites traded in the market are heat treated. Heat treatment, which is a stable and irreversible procedure, is considered to be a natural type of enhancement as it is a continuation of the processes that occur into the earth. Due to its hardness, tanzanite is suitable for all-purpose in jewelry.

Tanzanite is named after tanzania (the only known source for this lovely gemstone) and it's the rare violet-blue gem quality variety of the zoisite mineral group. This gemstone is routinely heat-treated to eliminate yellow, grey and brown tints.

Tanzanite is the birthstone for the month of december. All photos are taken in natural daylight with a macro lens in order to better capture details and to obtain sharper pictures. Magnified pictures though show flaws or inclusions/imperfections that are actually not visible by the naked eye. Please note that colors may vary slightly due to the color calibration of each individual monitor. All my gemstones and beads are natural unless otherwise stated in the listings.

Items may appear larger in pictures to show details, so please refer to the size or measurement in product descriptions. Feel free to contact me if you need any further information.

This item is made of tanzanite.
