A study of shape and shade, the Enigma diamond ring is a one of a kind band featuring natural coloured diamonds. Set on a curved 9 karat yellow gold band, a fancy green diamond, a champagne diamond, a fancy orange diamond, two fancy yellow diamonds and a round cut white diamond are the supporting acts to an unexpected surprise - a single princess cut white diamond. An unusual mix of cut and colour, this diamond ring can be stacked beside others or worn solo as a unique feature band.
