3 Diamond Necklace 

Our 3 diamond necklace provides a simple and classic Trilogy cluster pendant design styled with a trio of round brilliant-cut diamonds. We create each necklace individually to order, handcrafting the design from a choice of precious metals. Choose from 9-carat or 18-carat gold in white, rose and yellow gold variations. Or, for elegant luxury, choose 950 platinum, styled with a matching Venetian box chain. The chain inserts through the body of the necklace in a modern slider style emphasizing the simplicity of this modern necklace design. 

Diamond specifications for the 3 diamond necklace


By default, we create this dazzling necklace with a matching set of 3 x natural diamonds, all graded G colour and SI1 clarity.
