finally bought the last rock to complete my ring idea; needed another white one after giving the big diamond to my daughter. a diamond that size is out of my retired-school-teacher budget, so i bought a white zircon. went back to the same place that i got my loose sapphire-- great selection, good prices, good delivery!

I'm always real pleased with this website, I don't think there is much you could do to make it any better. I wish the shipping charges were lower, but it is understandable.

This is a site that sources valuable and genuine stones forms around the world, with and honest and descriptive sections, as well as specs, and the option to have the gemstone collection one might purchased—certified! Price ranges vary, but are always affordable and always worth it, whether it’s a gift, or for a personal business.

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
