What is a Black Diamond

Black diamonds, scientifically known as carbonado, are a rare and unique variety of natural diamond that appear completely jet black and opaque. They are made of pure carbon and share the same hardness level of 10 on the Mohs scale as regular black diamonds. Their black color comes from dark mineral inclusions such as graphite, pyrite, and hematite, which prevent light from passing through and give them a deep metallic shine. Structurally, they are polycrystalline, formed from millions of tiny diamond crystals fused together, making them harder to cut and polish than regular diamonds.

Proper care is essential to maintaining the beauty and longevity of loose black diamonds. Clean them gently using a soft bristle toothbrush with mild soap and warm water, and always avoid harsh chemicals or abrasive cleaners. Never use ultrasonic or steam cleaners as their vibrations and heat can cause cracking or chipping due to the polycrystalline structure of black diamonds. Store black diamond jewelry separately in a soft lined box or pouch to prevent scratches, and, avoid wearing them during heavy physical activities. It is also recommended to visit a professional jeweler at least once a year for a thorough inspection and cleaning to keep your black diamond jewelry in excellent condition for years to come.
