1.44 Art Deco Sapphire and Diamond Engagement Ring in Platinum.  This blissful Art Deco engagement ring features a 1.44 carat cushion cut natural sapphire and a halo of accent diamonds in platinum. The blue sapphire is a bright and highly saturated shade of Imperial blue. This gem has a great amount of fire from the chunky facets of its cushion cut pavilion. Connected by icy platinum prongs, the blue sapphire is accented by a halo of near colorless, natural diamonds. Two larger .15 carat diamonds accent the top and bottom of the sapphire and the halo is completed by ten .02 carat diamonds. The platinum band is strong and minimal, creating a strong support for the mounting of the natural gemstones. Reaching 4.86mm above the finger and weighing a total of 3.45 grams, this antique engagement ring is a one of a kind, cosmic beauty!
