Grandidierite is one of the world’s rarest and most enchanting gemstones, known for its mesmerizing blue-green hues and translucent glow. First discovered in 1902 in southern Madagascar and named after French explorer Alfred Grandidier, this extraordinary gem has remained elusive and highly coveted ever since.
Grandidierite’s unique color arises from trace amounts of iron, giving it a distinctive teal-to-aquamarine range that seems to shift depending on lighting and angle. Whether softly translucent or eye-clean and faceted, each stone is a celebration of rarity, beauty, and the geological marvels of Madagascar.
✦ Exceptionally Rare – Grandidierite ranks among the top 10 rarest gemstones on Earth, making each stone a true collector’s treasure.
✦ Unmistakable Color – Its delicate yet vibrant blue-green tones fall between seafoam and teal, evoking both tranquility and intrigue.
✦ Madagascar Marvel – Though trace finds have occurred elsewhere, Madagascar remains the premier—and most celebrated—source of gem-quality material.
✦ Symbolically Powerful – Often associated with truth, clarity, and personal growth, Grandidierite is cherished for more than just its rarity.
✦ Expertly Selected, Ethically Sourced – Every Grandidierite offered by Gallery Gems is hand-selected for its natural beauty, verified authenticity, and responsible sourcing.
Gem-quality Grandidierite is almost always found in small sizes, with inclusions common due to its crystalline structure. Transparent stones over one carat are extremely rare. Most available pieces are translucent to semi-transparent, which is part of their charm—and a key indicator of natural origin.
