The opals I ordered are absolutely beautiful, very fiery and well-cut. The pictures online didn’t do them justice. Shipping did take longer than expected (I chose the standard option), but the gemstones I received were definitely worth the wait.

Was a little darker orange than I wanted, but still lovely.

I have purchased gems from Gem Select twice a year, for more than a few years.Gem select is the best place to buy gems. The selection and presentation are genuine. What you see is what you get, keeping in mind the carat weight, and measurements they have listed. Never have I been disappointed with any gem I have received from them. Nan

GemSelect has a great selection of smaller cabochons. Many other retailers do not. Plus, the photo of the stone is the one you are purchasing. Shipping from Thailand is nearly as fast as from within the US. Stones are tightly and neatly packaged.

Picking a garnet to match a setting. Good selection, It would have been better if a side by side color comparison was possible.

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
