Diamond 28 Ct Blue Uncut Rough Diamond Loose Diamond for Ring- 5 g

Uncut rough diamonds are diamonds in their natural, unpolished state as extracted from the earth. Unlike the brilliantly faceted stones typically seen in jewelry, rough diamonds retain their irregular shapes and surfaces, offering a glimpse into the diamond's origin before processing. The blue coloration, seen in rare natural blue diamonds, is due to trace elements such as boron within the crystal lattice, making them highly sought after by collectors and connoisseurs alike. A 28-carat uncut blue diamond is exceptional both in size and color rarity. Such stones can be appreciated as collectors' items or potentially cut and polished into unique gemstones for fine jewelry, especially rings where a large, vivid stone creates a notable impression. The natural, uncut state accentuates the diamond's raw beauty and geological story.
