Diamond is the hardest stone on the Mohs hardness scale, meaning it scratches every other stone. Their name actually comes from the Greek word adamas, meaning unconquerable, due to this.
Diamonds are graded by the 4C’s: Color, Clarity, Cut, and Carat.
Diamonds can be colorless, yellow, brown, green, blue, red, pink, and black.
Famous diamonds include the Hope diamond, the Tiffany diamond, and the Cullinan 1 diamond.
Lab grown diamonds have been available since 1954, and the process has been refined several times.
Other options for natural stones besides diamonds include white sapphire and white quartz.
