Cushion Cut Diamond Ring, 1.60 Carats

This classic Harry Winston ring is set with an exceptional 5.56-carat emerald-cut diamond that bears all the hallmarks of the legendary Golconda diamonds. The rare stone is certified by the Gemological Institute of America (GIA) as being D color and Type IIa, meaning it lacks any trace of nitrogen. Nitrogen is the element that gives diamonds color, making this gem a full two shades whiter than the whitest D-color diamond. It is also one of only a handful of Type IIa diamonds that are also internally flawless, a distinction that enhances both its beauty and rarity. Set in platinum and accentuated with approximately 1.00 total carat of tapered white diamond baguettes, this ring is truly a treasure to behold.

Because they hailed from just one mine in the ancient Indian city of Golconda that ceased production hundreds of years ago, these stones are exceptionally rare, with only a relative handful known to exist. They are universally accepted as the finest diamonds in the world; the diamond in this ring shares all their best qualities. The House of Harry...
