Gem of the month
Just like the deep blue sea: our gem of the month in July is turquoise.
Turquoise belongs to hydrated copper/aluminium phosphates. This very rare gemstone is only found in dry, “low mineral” areas and is described as “stable” with a porous surface. On the Mohs Scale of hardness it rates 5 to 6.
Very few turquoises come in a deep turquoise blue or green. Many of them are covered with a so-called "matrix", a grey, brown or black net of veins which comes from their chemical composition.
The main countries of origin are Iran, China and the USA (Arizona and Nevada). However, most sourcing areas are currently shut down as turquoise has hardly been found for quite some time. Thus, especially “clean” turquoises with a very deep color have become extremely rare and precious.
History & Symbolism
Turquoise is one of the oldest gemstones in the world and was already mentioned as precious jewelry for the Pharaos of the ancient Egypt. The name comes from the French for "Turkish stone" and from its first trading area, Turkey. Turquoise is known as the “stone of protection and healing” and symbolizes good health and luck.
The clear turquoise color is a great splash of color for both dark and muted clothes as well as bright and vibrant fabrics. Combined with rose or yellow gold, it creates a great summer look and, with white gold, is very elegant.
Turquoises are very sensitive to light, oil, cosmetics and cleaning substances. They should never be worn while in contact with water. They should never be left too long in strong daylight. It is recommended to not mix turquoise with other jewelry to avoid scratches.
Clean with warm soapy water and avoid ultrasonic or steam cleaning.
