Frank Gardner Hale carefully selected and arranged gemstones to accentuate their natural shapes and dazzling colors. In this necklace, he expertly interwove gold, green garnet and sapphire stones to spotlight brilliant opal gems that seem to light up on their own. Circa 1910-1920. From The Susan Donald Collection.

Don’t cut corners when it comes to diamond cut! Here are some fun facts about diamond cut grades you might not know:

- Cut grades are based on seven factors: brightness, fire, scintillation, weight ratio, durability, polish and symmetry.
- Only round brilliant diamonds receive cut grades. All other shapes receive polish and symmetry evaluations.
- Cut might just be the most important of the 4Cs! An Excellent cut makes a diamond bright and lively. A Poor cut leaves it dull and lifeless.
- Thanks to GIA’s introduction of diamond cut grades, most diamonds on the market today have an Excellent or Very Good cut.
