Natural Spessartite

Spessartite is a rare form of garnet with an unusually high index of refraction. It has always been a rare stone. Recent discoveries in Mozambique and Nigeria led to an increase in production over the last two years. Although the output was significant, the percentage of fine material in larger sizes was very small. Current spessartite prices are near their historical lows but they are definitely rising. Some gem quality pieces are still available in Bangkok but production in Africa has declined.

There will be more spessartite but how deep will it be?, Will there be water to mine it? Will there be people to mine it? Will there be roads nearby? Any fuel for mining? Diseases? Surely they will find it but who knows when, where or, how much.
