Gray spinel is super popular right now, and why wouldn't is be? We have a lot of black and grays in our wardrobe to wear it with. Measuring 6 mm round, and 0.89 carat, it is set in a four prong crown in this 18 kt white gold Natalie K ring. Another 0.37 carats in diamond weight accents the spinel with a round brilliant cut and tapered baguette on each side. Size 6.75
