A beautiful blue topaz and diamond cocktail ring from the Petra fine jewellery collection by New York jewellery designer Kara Ross. A smooth cabochon-cut topaz is bezel-set in yellow gold and part covered by a layer of pavé diamonds. As if a diamond blanket is being pulled back to reveal the beauty of the sky blue topaz beneath, this intriguing blue gemstone cocktail ring is a true statement ring. Inspiration for Kara Ross' eponymous jewellery collections is found in the beauty of nature in all its forms, polished and unpolished, symmetrical and asymmetrical. The Petra collection plays with these concepts, sitting the two side by side and challenging our conventional perceptions of beauty.
