alluvial gemstone

Alluvial gemstones are natural minerals transported by water and deposited in riverbeds, gravel layers, and other sediment deposits over time. Sri Lanka is renowned for its alluvial gem deposits, which produce a variety of precious and semiprecious stones.

These deposits can contain blue sapphires, yellow sapphires, spinels, garnets, zircons, chrysoberyl, and other fascinating gemstones. Each stone has its own characteristics, including color, clarity, crystal shape, and potential for cutting.
