In the early 21st century, Madagascar generated about half of the world's sapphires following the discovery of a large deposit. It was not long after the discovery that the easiest-to-extract sapphires were removed and miners began digging more deeply to find additional gemstone deposits.
When found within a whole rock, a sapphire is considered part of a primary deposit. Sapphires discovered in stream beds, where they are released after a rock is fractured, are considered secondary deposits. However, over time, if a significant number of sapphires accumulate in a particular stream or river, the spot is known as an alluvial deposit. These are generally the most lucrative deposits for miners, as the high concentrations of gemstones are easy to remove. Those hunting for alluvial sapphires are able to do so with as little as a sieve, basket or pan. Most countries with significant quantities of sapphires strictly regulate the removal of the gemstone to avoid overuse of the land.Learn more about Jewelry & Watches
