Unbeknownst to many, four of the month in the year have more than one birthstone. March, June, October and of course December. It’s not entirely known why this has happened. Some believe it was done in order to offer a different or a more cost effective option for the month where the gemstone was rarer. Others believe it naturally occurred over time through different traditions blending together and instead of one gemstone being replaced by the other they both became popularized. For the month of December the birthstones are turquoise and tanzanite. Both gemstones are popular for their attractive vibrant blue colour and make the perfect winter pair.
Turquoise is an opaque mineral. The stone is used mostly in jewellery and ornamentation and is greatly valued for its vibrant blue-green colour. It’s a secondary mineral and forms during the oxidation of other stones. Due to its formation and its other properties a turquoise colour can widely vary. The familiar “turquoise” colour we know could also vary in hues but the blue is thought to be due to idiochromatic copper while the green can be either due to iron impurities or dehydration of the stone. Hardness and colour are it’s most valued characteristics. A solid uniform colour is sought after. Depending on the black veins through the mineral might decrease its value or they might not affect it. It is, however, rare for the black vein pattern on the stone to increase its value.
Turquoise might be one of the first stones used by humanity for decorative purposes. Generally protective properties have been prescribed to it. The Aztecs saw it as a stone of personal protection and would add it to armour and shields. Calming properties are also attributed to the stone.

Tanzanite is an incredibly rare variation of zoisite in a blue or violet colour. The gem was discovered in 1967 in Tanzania. Though misclassified at first it was identified as blue zoisite and re-named tanzanite by Tiffany & Co in order to market it better and highlight the gems exclusivity. Tanzanite is a great investment. As the gemstone can only be mined in one place in Tanzania, when the reserves of it become depleted there would be no new stones. As supply depletes, its price will only rise.
Mainly blue or violet in colour, if viewed in different lighting, tanzanite can appear to change colour. Properties prescribed to tanzanite are similar to those of turquoise. It is said to be able to calm and relieve stress as well as aid in concentration. Tanzanite is seen as a good gemstone for highly active people as it helps balance and redirect energy.
