Gemstones from Madagascar

Madagascar emerged as a major gemstone producer in the late 20th century and is now one of the world's most important sources. The island produces an extraordinary diversity of gem species, with notable deposits of sapphires (including fine pinks, blues, and bicolours from Ilakaka), rubies (from Andilamena and Didy), Paraíba-type tourmalines, and diverse garnets.

Madagascar Gem Highlights

  • Sapphire: major source of pink, blue, and bi-colour sapphires; very competitive prices.
  • Ruby: increasingly important; Didy rubies can show exceptional fluorescence.
  • Paraíba Tourmaline: copper-bearing tourmalines comparable to Brazilian material.
  • Tsavorite Garnet: vivid green; found in southern Madagascar.
