11th Anniversary: Turquoise: The Birthstone for December and 11th Wedding Anniversary Gem

 

Turquoise is the beautiful birthstone for December, alongside zircon and tanzanite, and also represents the 11th wedding anniversary. The name turquoise comes from the French word “Turkish,” as the mineral was first brought to Europe through Turkey in the 17th century.

 

This stunning gemstone is prized for its blue/green hues, with the blue color attributed to copper and the greenish tint caused by the presence of aluminum. Turquoise forms over millions of years when water interacts with iron-rich limonite or sandstone containing copper and aluminum minerals. It typically has a MOHS rating just under 6, similar to the hardness of window glass.

 

Many turquoise stones feature unique vein-like markings, known as the matrix, which are formed by the host rock. Limonite creates dark brown veins, while sandstone produces tan markings, adding to the gemstone’s natural beauty and individuality.

 

Whether you’re celebrating a December birthday or an 11th anniversary, turquoise makes a stunning and meaningful gift.
