April stones in detail

Diamond

Composition Pure carbon (C) in cubic crystal structure
Hardness · Crystal system 10 · Cubic
Mined in Botswana, Russia, Canada, South Africa, Australia

The hardest natural substance — but hardness is not toughness. A diamond will scratch anything, and still cleave if struck along its grain.

Traditionally associated with clarity, permanence and commitment.

Care. Soapy water and a soft brush — diamond attracts grease and loses sparkle fast. Safe in ultrasonic.

Spotting a fake. The fog test is the quick one: breathe on it. Diamond clears almost instantly while cubic zirconia and moissanite stay fogged a second longer. Moissanite also shows doubled facet edges under magnification.
