Physical properties

Formation & geological history

Diamonds formed deep in Earth’s mantle under extreme pressure and heat, mainly more than 1 billion years ago; lab-grown examples crystallize by HPHT or CVD methods over weeks. The image cannot establish natural versus synthetic origin.

Uses & applications

Used primarily in jewelry for brilliance and durability; diamond also has major cutting, drilling, and abrasives applications. Value depends heavily on carat weight, cut, clarity, color, metal, and certification.

Geological facts

The stones appear pavé/channel-set in a modern ring, but image resolution prevents reliable grading or species confirmation. A gemological report and testing are required to distinguish diamond from cubic zirconia or moissanite.

Field identification & locations

Identify by exceptional hardness, strong brilliance, sharp facet reflections, and thermal/electrical testing; visual inspection alone is insufficient. Common natural sources include Botswana, Canada, Russia, Australia, and southern Africa.
