I was looking for a gem to put in my grandmothera's necklace for an event. GemSelect made it easy to narrow down what I was looking for, had a great price, and was very convenient.

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.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
