This beloved gem may be quite colorless or strongly tinted with a variety of hues. Champagne and Yellow Canary Diamonds have recently gained much popularity. The diamond remains the most popular gem chosen for engagement ring settings. The crystals are generally octahedrons, though sometimes they have a cubic or dodecahedral formation. Their superior hardness and brilliance when faceted make them the stars of the gem trade.Diamonds derive their name from the Greek Adamas, meaning invincible.
