    This Burmese Ruby may be heated, but the intense red hue, the extraordinary cut, and the perfect Asscher-cut dimensions make this 4.21ct Ruby regardless a very impressive stone. The size alone would make this a very rare ruby, but all factors combined make it rare and desirable. Have our in-house designers and master jewelers create an incredible piece of jewelry to properly display this wonder of nature. The Asscher cut, created in 1902 as a diamond cut by the Asscher Brothers of Holland, is a square emerald cut, and because of its square shape often takes on the appearance of an octagon. Owing to the symmetry of the cut, stones cut as Asschers are able to send more light and color to the eye.
