One of the world’s oldest stones, December’s birthstone, turquoise, plays an important role in ancient and modern culture. Treasured by groups ranging from the Egyptians to the Native Americans, turquoise is thought to be a healing gem. Whether you’re interested in turquoise for its protective properties or simply its rich blue colour, there are plenty of beautiful options in Sotheby’s upcoming jewels sales. – Stephanie Sporn
