Site worked well and helped me find a rock that matched what I was looking for. Well within budget and I trust it will show up, so that's definitely positive. Not much else to it. Satisfied.

I liked the selection of gems, and price. I did not like your PayPal process. I already have a PP account and you want me to sign up for another.

I love the ability to choose from many options of shapes, gemstone type, color, and so forth. It is fun!

The citrine gems are beautiful. I appreciated that each stone was individually shown on the website so I could see exactly what I was getting. No mystery person selecting random stones for me. The documentation included with each gem was high quality as well. Great price and arrived as expected.
