Estate Platinum Old Mine Cut Diamond & Synthetic Blue Sapphire Art Deco Engagement Ring

Crafted in platinum, this Art Deco estate ring is centered by an old mine cut diamond measuring approximately 6.01 x 6.56mm and weighing approximately 0.95ct, H color, SI2 clarity. The center stone is framed above and below by eight synthetic blue sapphires totaling approximately 0.15tcw, with four single cut diamonds set into the geometric shoulders: two measuring 1.8mm (approximately 0.05tcw) and two measuring 1.6mm (approximately 0.03tcw), all H color, SI2 clarity. Total diamond weight is approximately 1.03tcw. The ring is a size 5.25 and weighs 3.7 grams.

The old mine cut is a hand-cut diamond shape recognized by its softly squared cushion outline, high crown, small table, and open culet. Cut by eye rather than to modern mathematical proportions, each old mine diamond has its own character, with broad, chunky flashes of light rather than the fine sparkle of a modern brilliant. The synthetic sapphires share the same chemical composition and hardness as natural sapphire, providing a saturated blue border that sharpens the outline of the center stone. Milgrain edging and an open gallery complete the geometric design.

A refined choice for collectors of Art Deco jewelry or anyone seeking an engagement ring with genuine antique-cut character, this platinum ring pairs the warmth of an old mine cut diamond with a crisp frame of blue. It would make a meaningful gift for an engagement, anniversary, or milestone occasion.
