Grs & Gil Certified Cobalt Blue Spinel and Diamond Ring
About the Item
Among all Rare Blue Gemstones, the Cobalt Spinel possesses unique beauty factors such as sparkle, brilliance, unparalleled color tone and other physical and chemical properties. The ratio of the size, quantity and demand for Cobalt Blue Spinel is extraordinary.
Putting all the factors together, Cobalt Spinel is perhaps the most expensive blue gemstone in the contemporary world. Blue Sapphire can compare only in color tone, but not in rarity or price. Blue Diamond cannot get close to the supernatural blazing Blue tone of Cobalt Spinel.
The pear-shaped cobalt blue spinel weighing 3.00 carats, to the stylised ring shank decorated with round brilliant-cut diamonds; mounted in 18 karat white gold; ring size 6½
Accompanied by a GRS report numbered GRS2022-032749, dated 21 April 2022, stating that the 3.00-carat Cobalt spinel is natural, Blue colour, with no indication of heating.
Accompanied by a GIL report numbered STO2022110551510, dated 5 November 2022, stating that the 3.00-carat Cobalt spinel is natural, Blue colour, of Tanzanian origin, with no indication of thermal treatment.
