Petra Split ring with raw blue opal, raw hemimorphite and diamonds

EDITOR'S REVIEW

American jewellery designer Kara Ross has an enviable portfolio of high-profile clients, including Michelle Obama. Her Petra fine jewellery collection is audacious and energetic, combining rough and smooth gemstones to great effect. This Petra Split ring contrasts a gorgeous iridescent blue opal with the chalky texture of raw, natural, watery blue hemimorphite. Separated by a wavy band of accent diamonds, the ring evokes the turquoise blue of the Mediterranean and would look sensational on a hot summer night.
