DIAMONDS AND COLOURED DIAMONDS

One of the most classic gemstones, diamonds, is celebrated for their beauty, purity and superlative strength that stands the test of time. These sparklers are judged mainly by the four Cs—carat, colour, clarity and cut. Meanwhile, modern classification divides diamonds into two main types: Type I and Type II, with the latter, lacking in detectable nitrogen, into two groups – IIa and IIb. Type IIa diamonds are the most chemically pure form of diamonds. They are exceedingly rare, representing less than 2% of the world’s production of gem-quality diamonds. The most prominent lot in this section is a stunner of such calibre: a magnificent 50.62 carats Marquise-cut D coloured VVS2 clarity (potential) Type IIa diamond.

The sale also offers a diverse number of coloured-diamond jewels, including a unique Belle Époque 52.26 carats fancy intense yellow cushion-shaped diamond, a pair of 5.64 carats fancy intense green and 5.18 carats fancy intense yellowish green diamond earrings, as well as a fancy pink internally flawless clarity Type IIa diamond weighing 5.42 carats.
