Here is a large rough diamond crystal of unusual cubic form, untouched by tools or hands, and completely natural. This thumbnail specimen boasts a sculpted cubic form with ridges and edges that bring the piece to life, helping to aid the dimensionality of the piece, accented by the glimmering adamantine luster. A warm honey-amber color glows on the piece with minor iron mineral staining. A hefty size for a diamond thumbnail weighing 18.71 carats. 18.71 ct, 11.86 x 11.32 x 10.92 mm.
