This magnificent stone exhibits a very unusual and quite rare carbon pattern which can be clearly seen in each of the eight faces of this polished diamond. The carbon pattern is a hexagon with a smaller clear hexagon in the centre. This hexagon pattern is quite fascinating and marks the diamond as truly unique and one-of-a-kind. The diamond has been polished to keep the natural crystal shape and to highlight the hexagonal carbon pattern within the stone. The diamond has a tint of yellow colour. It is a singular stone, exceptional in size and characteristics, a very noteworthy diamond. This diamond is definitely one for the collector of rare and unusual gemstones. There is also no reason whatsoever it couldn’t be set in some amazing ring if that is your desire. An awesome diamond in every regard.
