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 Bullet shaped piece of Blue Turquoise measures 3cm x 1cm approx and is suspended from an 18 Inch 925 Silver chain. Beautiful Blue Turquoise is One of Three birthstones for the month of December (in addition to Zircon and Tanzanite).
