Diamond 1.59 CT Natural Brown Rough- 0.32 g

Natural brown rough diamonds represent uncut diamonds in their raw state before polishing and faceting turn them into the bright stones commonly seen in jewelry. Brown diamonds, sometimes called champagne or cognac diamonds when cut and polished, derive their color from structural lattice defects or minute inclusions rather than impurities. This 1.59-carat rough diamond weighs about 0.32 grams and maintains its natural crystal form, often octahedral or irregular shapes with a distinct adamantine luster. Raw brown diamonds hold interest for both collectors and jewelers who appreciate their natural charm and potential for cutting into stones with unique warm tones. Though less traditionally valued than colorless diamonds, brown diamonds have gained popularity for their earthy colors and durability, scoring a 10 on Mohs hardness scale. Rough diamonds like this offer insight into the geological processes deep within the Earth where carbon atoms crystallize under extreme heat and pressure to form these enduring gemstones over billions of years.
