April Birthstone - Diamond


The term diamond comes from the Greek "adamas", meaning unconquerable, a fitting description for the hardest gemstone known to man. Diamond is essentially pure carbon that has crystallized under enormous heat and pressure through volcanic activity. Until the 19th century only men wore diamonds but, when Agnes Sorel, mistress of King Charles VII of France, began wearing them, it became a fashion for women also.

Diamonds were once considered a talisman against phantoms and nightmares, and were supposed to give soldiers courage and virtue.  Now, diamonds are given as gifts of eternal love and devotion.

Wearing Cautions: Diamonds are very tough, but not indestructible. If severely impacted, diamonds can chip or break along a grain line. This is a very uncommon occurrence.

Cleaning Cautions: Store bought jewelry cleaner works fine to clean diamonds. Do not use toothpaste or any abrasive. This won't hurt the diamond but will scratch the mounting.
