Natural Rough Diamond Value Guide

Natural rough diamonds are ancient carbon treasures formed over billions of years, prized by collectors for their raw crystalline structure and geological history. Unlike polished gems, these specimens retain their irregular shapes and inherent textures, reflecting their origins in regions like Botswana, Russia, or Canada.

What affects the value of Natural Rough Diamond?

• Carat weight and overall size significantly impact the $250-$300 price range for these raw specimens.
• The clarity and presence of internal inclusions visible within the rough stone affect its desirability.
• The specific crystalline habit and symmetry of the rough shape can increase its value to mineral collectors.
• Color saturation, ranging from colorless to various tints, plays a crucial role in determining the market price.

How to Identify Natural Rough Diamond?

• Look for a distinct crystalline structure, often appearing as octahedral or cubic shapes in their raw state.
• Examine the surface for a greasy or adamantine luster that is characteristic of natural carbon diamonds.
• Check for unique surface markings like trigons, which are small triangular indentations found on the faces of rough diamonds.
• Verify the hardness; as the hardest natural substance, a rough diamond will not be scratched by other minerals.

History of Natural Rough Diamond

Diamonds are thought to have been first discovered in India around 4th century BCE. They were initially valued for their strength and used as tools, and only later for their brilliance as gemstones. Ancient civilizations believed diamonds were splinters of stars or tears of the gods. The journey of a rough diamond from the earth to a polished gem is a testament to natural geological processes and human craftsmanship.
