Physical properties
Hardness: 10 (Mohs); Color: Colorless (in this specific piece); Luster: Adamantine; Crystal structure: Cubic; Specific gravity: 3.52.
Formation & geological history
Formed under intense heat and pressure deep in the Earth's mantle (100+ miles below the surface) and brought to the surface via volcanic eruptions through kimberlite and lamproite pipes.
Uses & applications
Primary use in fine jewelry (engagement rings) and high-end collectibles. Industrial uses include cutting, grinding, and drilling due to extreme hardness.
Geological facts
Diamonds are the hardest known natural material on Earth and can be over 3 billion years old. While traditionally clear, they can occur in various colors due to trace impurities.
Field identification & locations
Identify by its brilliance, ability to scratch sapphire/corundum, and thermal conductivity. Often found in South Africa, Russia, Canada, and Australia.
