Golconda Type IIa diamond flanked solitaire ring. Centrally set with a round old cut Golconda Type IIa diamond, D colour, VS1 clarity with an approximate weight of 1.02 carats in an open back claw setting, further set with eight round eight cut diamonds in open back grain settings with a combined weight of 0.08 carats. The total approximate diamond weight is 1.10 carats, to an elegant flanked solitaire design featuring curving claws, an intricately pierced gallery and fancy shape open backholing, flanked by openwork raised shoulders with millegrain edging flowing down to a solid tapering D-shape shank. Tested platinum, circa 1910, accompanied by Gemological Institute of America (GIA) report #5202803312. The origin, type colour and clarity of this diamond make it one of the finest in the world.

Diamonds are classified by scientists into two main types, depending on the presence of nitrogen in the diamond's chemical makeup. Type II diamonds contain little to no such impurities. This type is further subdivided into two groups, ‘a’ and ‘b’, both of which make up less than two percent of all gem quality diamonds. Type IIa diamonds are extremely rare, and the most pure of all diamonds, and consequently exhibit superior transparency. This type was first identified as coming out of India, namely the Golconda region. Some of the most famous diamonds in the world are Type IIa, including the Koh-i-noor and the Cullinan I.
