Lot Essay

Type IIA diamonds are rare gems of the diamond family which have no traces of the colorant nitrogen. The absence of this element, seen in 98 of diamonds, gives the stone a purity of colour and degree of transparency that is observed only in the finest stones originating from the fabled mines of Golconda, Brazil and South Africa.

This oval-shaped diamond of 20.30 carats has been cut to near perfect proportions and has been graded D colour with internally flawless clarity, a distinction reserved only for the finest gems in the world.
