Madagascar The most recent discoveries of rubies have occurred in Madagascar at Andilamena and Vatomandry. Indeed, the discoveries are only months old. The deposits differ significantly with respect to their mineralogical and gemological properties. The deposit in Vatomandry produces crystals of nice natural orange/red and pinkish color which do not require heating. The deposit is secondary and the material appears to have been transported from the original source rock.

The deposit in Andilamena is more substantial and seems have been the focus of most of the recent production. The rough is generally somewhat violet and not very clean. Heat treatment can dramatically improve the color and many of the resulting stones will show a pure red similar to rubies from Thailand and Burma.

The actual mining is about 85 kilometers to the north near the national park but Andilamena is the only town in the area. Like many parts of Madagascar, there are gems but no roads to go get to them and most people just walk. The deposit is of a primary character and probably igneous in origin.

Madagascar will probably continue to be a major source of ruby rough. Other deposits in uninhabited areas of north central and eastern and western Madagascar have also been reported.

Ruby has been the world's most valued gemstone for thousands of years. It was said to be the most precious of the twelve stones God created when he created all things and this "lord of gems" was placed on Aaron's neck by God's command. Ruby brings you serenity, and protect against injury.
