Natural blue rough diamond - sparkling - 3.31 carats - No reserve price Rough- 0.66 g

Natural blue rough diamonds are among the rarest and most captivating types of diamonds. Their distinctive color originates from trace amounts of boron within the diamond's crystal lattice, which absorbs red, yellow, and green light, giving the stone its unique blue hue. Unlike polished diamonds, rough diamonds are in their natural, uncut state, retaining their original crystal form, often octahedral or cubic. This 3.31-carat blue rough diamond glistens with natural sparkle due to its facets and internal structure, even before any cutting or polishing. Blue diamonds have long been coveted for their rarity and beauty, often associated with royalty and high-value jewelry. Their unique color and scarcity make them highly sought after by collectors, gemologists, and investors. Given its natural unsettled form, this specimen offers insight into the mind-boggling geological processes that take place deep within the Earth's mantle, where such diamonds are formed under extreme pressure and temperature conditions over billions of years.
