Medieval Fantasy RPG -

Red Diamonds - This extremely rare gem is actually purplish red with a clarity that is brilliant even compared to a dragon's eye diamond. They sparkle with a shimmering red light.

Only a very few red diamonds have ever been found, and few people have ever even seen one. A Secret Mine somewhere in the world produces a small number of red diamonds. The largest and finest of these are auctioned every year or two, and sell for millions of gold.
