Rep your birth month with our 9ct Gold December Birthstone Round Claw Tanzanite CZ Necklace. Sitting perfectly on a Blecher style chain, the 4.5mm stone in tanzanite colour, is truly beautiful and would make a thoughtful gift either for yourself or your loved one! We like the fact is has a bolt ring clasp as it feels secure whilst remaining delicate and dainty. The 375 metal stamp indicates the purity of the gold and gives it that seal of approval from us!
