Like diamonds, white sapphires are available in different qualities. Sapphires are generally rated on three qualities, A, AA, and AAA. We strongly recommend AAA white sapphires, which are the highest quality of sapphires available. Unfortunately, while this grading system used to be universal sign of quality, it is no longer the case and there are variations within the AAA quality. The color and clarity sections below will advise you on what the best way to check for a AAA stone is.

Evaluating color in white sapphires is important. Many a times, white sapphires will have a yellow or blue hint. While this may be desirable to some, in general top quality (AAA) white sapphires will not show much of a hint and should look colorless overall. The color chart below provides a general guide for evaluating color in round diamonds, based on grading.

White sapphires, because of their colorless nature, are most often compared to diamonds, moissanite, and white topaz. White sapphires are a very durable stone and are the second hardest natural stone in the world, only falling behind a diamond. White sapphires have a more stone like appearance than diamonds and moissanite though with the sparkle being more white in color, instead of exhibiting rainbow flashes. The table below compares white sapphires to diamonds, moissanite, and white topaz.
