A Spectacular Diamond Ring Offered in Jewels Online | June 16-30

The combination of a diamond’s unparalleled hardness and crystalline purity has merited its celebrated status and established the stone as the pinnacle of all gemstones. The spectacular 28.86 carat D colour VVS1 clarity emerald-cut diamond ring ($1,000,000-2,000,000) presented in Jewels Online (June 16-30) possesses a purity of colour and transparency which can only be found in world’s finest natural diamonds. The diamond also belongs to the rare Type IIa category, which is extremely rare, making up less than 2% of all diamonds.  These rare diamonds have been unearthed from only a limited number of sources around the world, deeming this stone a miraculous phenomenon.

Type IIa diamonds are the most chemically pure and are characterized by their exceptional transparency. These stones are incredibly rare gems of the diamond family and have no traces of the colourant nitrogen.  The absence of this element gives the stone a purity of colour that is observed only in the finest stones originating from the fabled mines of Golconda, Brazil and South Africa.

The shape of the stone, the emerald-cut, is one of the oldest diamond shapes with stylistic origins tracing back to the 1500s. During the Art Deco movement in the 1920s, the cut was modernized based off a shape initially created for emeralds, thus the name, and the style rose to popularity. Today, the sleek look of an emerald-cut diamond, with its elongated, step-cut facets, is admired all over the world.
