Natural Rough Octahedron Diamond Value Guide

This natural rough octahedron diamond showcases the classic eight-sided crystal habit formed billions of years ago in the Earth's mantle. Sourced from South Africa, this specimen is highly collectible for its distinct greyish-metallic hue and raw, unpolished geometric structure.

What affects the value of Natural Rough Octahedron Diamond?

• The precision and symmetry of the natural octahedron crystal shape significantly impact the $110-$120 valuation.
• Clarity and the presence of internal inclusions visible through the greyish-metallic surface.
• The overall carat weight and physical dimensions of the unpolished carbon structure.
• The preservation of the crystal's natural surface skin and lack of mechanical damage from mining.

How to Identify Natural Rough Octahedron Diamond?

• Look for the characteristic eight-sided double pyramid shape known as an octahedron habit.
• Verify the unique greyish-metallic hue which distinguishes this specific South African rough specimen.
• Inspect for trigons or small triangular indentations on the crystal faces, a hallmark of natural diamond growth.
• Confirm the cubic habit and raw surface texture that indicates the stone has not been artificially faceted.

History of Natural Rough Octahedron Diamond

Diamonds formed billions of years ago under intense heat and pressure deep within the Earth's mantle. Rough octahedrons like this one are the most common natural crystal habit for diamonds and have been prized as talismans and decorative objects for centuries before modern facet-cutting techniques were perfected.
