Tanzanite

Tanzanite is a relatively new gemstone, first being discovered in Africa in 1962. Named after the country in which it was found, tanzanite has grown in popularity over the past several years, and is especially prized by those who have an eye for the elegant and unusual. Tanzanite has become a contemporary alternative to a diamond and is frequently the focal point in modern engagement rings.

Colour

Tanzanite ranges from light to dark violet‐blue, bluish‐purple and even pure blue. Rich, deep hues are the most valuable. Tanzanite is also a pleochroic gem, meaning it displays different colours in different directions.

Gem Family

Tanzanite is a variety of zoisite.

Hardness

Tanzanite rates a 6.0‐7.0 on the Mohs scale. Care should be given while wearing tanzanite jewellery.

Treatments

Nearly all tanzanite is heat treated to reduce any brownish tones, deepen its blue colour and enhance clarity.

Care

Tanzanite should be stored separately to keep from being scratched by other gemstones. Store them in a lined box or a soft pouch. Avoid steam and ultrasonic cleaners. Clean your tanzanite jewellery using warm soapy water and dry with a soft, lint‐free cloth.
