Natural Rough Grey Diamond Value Guide

This natural rough grey diamond is a compelling collectible that showcases the raw, octahedral crystal structure formed billions of years ago in the Earth's mantle. Originating from South Africa, this specimen represents the authentic state of a diamond as it emerges from a kimberlite pipe, offering a glimpse into the mineral's prehistoric origins.

What affects the value of Natural Rough Grey Diamond?

• The preservation of the natural octahedral shape significantly impacts the $450-$495 valuation range.
• Clarity levels and the consistency of the grey coloration throughout the translucent crystal.
• The overall carat weight and the structural integrity of the specimen's edges and points.
• Geographic provenance, specifically the desirability of South African kimberlite pipe origins.

How to Identify Natural Rough Grey Diamond?

• Look for the distinct eight-sided octahedral crystal habit characteristic of high-quality natural rough diamonds.
• Verify the specific grey tint and translucent clarity which distinguishes this South African specimen from industrial boart.
• Examine the surface for trigons or natural growth marks that occur during the carbon crystallization process.
• Confirm the material hardness; as pure carbon, it should easily scratch any other mineral or gemstone surface.
