GIA Certified 12.23 Carat Unheated Blue Sapphire and Diamond Platinum Ring


This platinum ring features a gorgeous royal blue color sapphire (12.23cts) set with 2 half-moon shaped diamonds that weigh a total of 1.50cts. The diamonds are fine quality; VVS-2 clarity and D-E color. The sapphire is accompanied by both AGL and GIA laboratory certificates stating it is unheated, from Sri Lanka. Under magnification, one can see the natural "silk" that intersects at sixty degrees, proving it is unheated. It is a fine quality gemstone in every respect: beautiful royal blue color, eye clean and expertly cut. It is very symmetrical and is not cut deep, enabling the ring to sit low on the finger.
