A “super spiral” cut, color-change garnet. These pyrope garnets from Morogoro, Tanzania change color from purplish-pink under incandescent light (Image 1) to purple under daylight-equivalent light (Image 2). This phenomenon is believed to be caused by higher than normal amounts of vanadium and chromium. The larger the stone, the more noticeable the color change. The super spiral cut stone weighs 15.25 carats and comes from the same material as the 42.42-carat rough crystal next to it. Color-change garnets of this size, intensity, and clarity are incredibly rare. Learn more: https://bit.ly/2LhNGwy

Natural yellow gem diamonds are the most common of the fancy-color diamonds, while orange diamonds are among the rarest when they have unmodified hues. Both categories owe their coloration to atomic-level lattice defects associated with nitrogen impurities in the diamond structure. Four major groups of defects are responsible for the color in nearly all yellow and orange diamonds: cape defects (N3 and associated absorptions), isolated nitrogen defects, the 480 nm visible absorption band, and H3 defects. Nitrogen-bearing diamonds are thought to incorporate isolated nitrogen during growth by substitution for carbon, meaning that natural diamonds start out with yellow to orange color. However, only the very rare type Ib diamonds maintain that original color. With time at high temperatures deep in the earth, the nitrogen atoms in most diamonds aggregate, resulting in either near-colorless stones or yellow diamonds colored by cape defects. Yellow and orange diamonds can be grown in a laboratory or created by color treatments, so a thorough understanding of the defects responsible for color in the natural stones is critical for identification. Yellow diamonds serve as the best ambassador to the colored diamond world due to their abundance and maybe the only colored diamond many people will ever see in a jewelry store.

GIA has graded some of the most remarkable diamonds in the world. The 14.83 carat Spirit of the Rose diamond - graded Internally Flawless, Fancy Vivid purple-pink by GIA - is the largest purple-pink diamond to ever appear at auction and commanded US$26.6 million at auction in November 2020. Its name derives from dancer Vaslav Nijinsky’s legendary performance in the Russian ballet, Le Spectre de la rose. The ballet tells the story of a young girl who falls asleep after attending her first ball and dreams of dancing with the spirit of a keepsake rose. Gary Schuler, Worldwide Chairman of Jewelry at Sotheby's, says of the stone: "the numerous facets and shades of pink dance in front of your eyes in a mesmerizing way." The stone's name not only refers to its color but also celebrates the fact that it was cut from the largest pink diamond crystal ever mined in Russia - the 27.85 carats Nijinsky rough.
