How can you test a raw diamond at home?
Scrape the crystal against a piece of corundum. Purchase a cheap piece of corundum or buy a mineral testing kit that includes corundum. Hold the corundum firmly against a table and scrape the suspected diamond against the corundum. If it creates a visible scratch, the crystal is a diamond.
How can you tell if a diamond is real or cubic zirconia?
