The World's Largest Sapphire Deposit
Hidden in the heart of Isalo lies the small village of Ilakaka, home to what is recognised as the world's largest sapphire deposit.
Stretching over thousands of square kilometres, this is a secondary deposit, meaning that millions of years ago, powerful geological and climatic processes naturally released sapphires from their original host rock. Carried by ancient rivers, the gemstones gradually accumulated in what is now a vast fossil riverbed that dried up approximately one million years ago.
This extraordinary geological history is what makes Ilakaka so unique. Even today, every excavation carries the excitement and hope of uncovering a hidden treasure a remarkable sapphire that has remained untouched for millions of years.
