Discover the World's Rarest Blue-Green Gemstone

Grandidierite is one of the most rare gemstones on Earth. Gem grade stone is hardly to get. 

Why Grandidierite is So Exceptionally Rare:

  • Extreme Scarcity: Gradnidierite is found in only one location worldwide - the remote regions of Madagascar - making it rarer than diamonds, emeralds, or rubies
  • Geological Marvel: Formed under incredibly specific conditions over millions of years, requiring the perfect combination of boron, aluminum, and magnesium in metamorphic environments
  • Limited Discovery: First discovered in 1902 and named after French explorer Alfred Grandidier, gem-quality specimens remain virtually impossible to find
  • Collector's Holy Grail: Most grandidierite exists only in museums or private collections of serious gem connoisseurs

What Makes This Stone Extraordinary:

This 103-carat rough grandidierite displays the stone's signature pleochroism - appearing blue-green from one angle and colorless from another. The mesmerizing optical phenomenon occurs due to its unique crystal structure, creating an almost magical color-changing effect that captivates viewers.

Perfect for faceting or cabbing, this exceptional rough material offers the rare opportunity to create a truly one-of-a-kind finished gemstone. Whether you're a lapidary artist, collector, or investor, this grandidierite represents both artistic potential and significant rarity value.

Own a piece of the impossible - grandidierite so rare that most gemologists will never see it in person.
