This 18 karat yellow gold and platinum Edwardian era cocktail ring features a 1.01 carat old mine cushion cut pink sapphire in a bezel setting, surrounded by four 3.0mm natural diamonds with I/J color and SI1-SI2 clarity. The two-tone metal construction creates contrast between the gold and platinum, and milgrain detailing adds texture along the edges. The pink sapphire creates a bold center stone that makes it stands out.
