Natural rough diamond Gray-Brown - 4.05 carats - No reserve price Rough- 0.81 g

Natural rough diamonds in their uncut state offer an intriguing glimpse into the early form of the world's most famous gemstone before shaping and polishing. This particular diamond is gray-brown in color, a less common hue among diamonds that may interest collectors and gem enthusiasts seeking unique specimens. With a weight of 4.05 carats, it represents a sizable rough diamond, preserved in its natural form. Rough diamonds typically display an irregular, octahedral crystal habit, sometimes with a dull, earthy surface due to their unpolished nature. Such uncut stones are valuable both as potential gemstones once cut and polished, as well as for educational and collecting purposes, illustrating the natural beauty and complexity of diamond crystals. The lack of a reserve price suggests it is offered with openness for bidders interested in raw diamond material.
