I believe this market could grow very large in the wake of cryptocurrencies as gold and silver become less popular. I believe birthstones will begin to increase in popularity for jewelry and meaningful trinkets. I think this website should consider another metric that gauges how "raw" the mineral/gem/stone/etc. is-- how processed it has been. Some people may want to get the raw material from a specific location, know its history, and contract someone to refine it into a personal keepsake.
