A World of Colors: Discover the Magic of Fancy Sapphires

Welcome to the realm of colors:

The world of sapphires is as vast as a lush garden, filled with colors ranging from deep midnight blue to ruby red. Beyond these classics, we delve into the splendid variety of fancy sapphires, which shine in all the colors of the rainbow, reminiscent of the beauty of exotic flowers and enchanted forests.

A Chromatic Revolution:

The late 20th century marked a golden era for sapphire discovery, with new deposits in East Africa and Madagascar revealing a surprising palette of sunny yellows, vibrant oranges, delicate pinks, and mysterious purples. These findings inspired designers to push beyond traditional color limits, creating jewelry that are true contemporary masterpieces.

Quality and Characteristics of Fancy Sapphires:

The evaluation of a fancy sapphire is primarily based on its unique coloration, which owes its existence to the presence of elements like iron, titanium, and chromium in varying proportions. Purity, precise cut, and originality of shape further influence its value, making each piece an invaluable treasure for connoisseurs.

Preferred Shapes and Sizes:

These sapphires vary not only in color but also in shape, with cuts ranging from the classic oval and round to more adventurous forms like the drop cut and antique cushion. Gems larger than five carats are rare, making them even more precious and sought after.

Color Palette of Colored Sapphires:

  • Padparadscha: An enchanting mix of pink and orange.
  • Pink: Hue due to chromium, sometimes titanium.
  • Purple: Created by varying combinations of iron, titanium, or chromium.
  • Orange and Yellow: Color from iron and possibly chromium or color centers.
  • Green: A complex color from the fusion of iron-induced yellow and blue from iron-titanium charge transfer.

Deposits:

The most important sources of fancy sapphires are Sri Lanka, Thailand, Myanmar, Australia, and Montana in the USA. The "younger" deposits are found in Africa and Vietnam.
