  • Catalogue Essay

    This magnificent diamond ring offers the highest pedigree in both design and importantly, composition. At an impressive 10.23 carats, the diamond is D colour, Internally Flawless clarity and of excellent proportions. It also has the added and important classification of being a Type IIa diamond. Type IIa diamonds are the most chemically pure diamonds and are known to display exceptional optical transparency. They are exceedingly rare, and amount to less than 2% of gem diamonds in the market. Type IIa diamonds were first known to originate from the famed mines of Golconda, India, but have since been recovered, albeit rarely, in all major diamond-producing regions of the world.
