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.

I found the filter options excellent. Yours was the third site I visited (asked chat got for reputable online sellers of loose gems) and the first I purchased from as I was able to easily find what I was looking for.

I purchased 4 gemstones in different sizes to be able to make a family ring for my granddaughter. I got exactly what I saw and they are absolutely beautiful! Shipping was quick compared to other gem stores I have dealt with! I will definitely order more stones from your company, as I am a collector and have several stones. You are my new go to company in the future
