Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.

First time using this website. It was both exciting finding things in my price range and things Iam gonna save up for and use in other pieces. I love that the picture of the gem is the exact gem I'll be buying. I haven't tested the gems yes but they said they sold me 100% natural gems.

I was looking for a small gift for a friend- the process is the same as every other time and was very simple, and she even got her gift early! On the downside, there's no way to easily keep track of multiple Shipping Addresses, so if I want to send a gift to Friend A and to Friend B, I have to overwrite everything and it's a fair bit clunky in that regard.

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.

The purchasing process is fairly quick and straightforward and for me user friendly so it probably took more or less than 3 minutes to purchase and pay for the items. I wish there was a discount offer for multiple items to encourage us buyers to purchase more an incentive and add more sales in your end. Besides that, it's been a great purchasing experience and will continue to shop as I am a repeat customer and have bought from your store many times before. Thank you.
