The deep blue hues of the turquoise crystal call upon the powerful yet infinitely gentle energy of the ocean and the most expansive skies. It symbolises wisdom, prosperity, tranquillity, and protection. In plainer and more scientific terms, the turquoise crystal is a hydrous phosphate of aluminium and copper. This Blue Turquoise Bullet and Blue Turquoise ball are set in Silver mounts. The Bullet measures 3.5cm x 1cm approx and the ball measures 1cm in diameter approx. They are suspended from a 19 Inch 925 Silver chain. Beautiful Blue Turquoise is one of Three birthstones for the month of December (in addition to Zircon and Tanzanite).
