Client Reviews

Reliable product quality and customer service allow us to gain customer approval

I've been wholesale AuGain's loose moissanite because it's the only brand I trust in China. My colleagues visited their factory in person and were impressed with their advanced equipment and workshop environment. During the sourcing process, they can communicate the details well, deliver on time, but at a lower price than some parts of Southeast Asia. Another point is that my consumers are very excited about owning beautiful moissanite jewelry, so I have high expectations for the quality of products from wholesalers, but AuGain has never disappointed me.

During the entire procurement process, AuGain made me look forward to it very much. Their salesperson is very professional. I showed my friends that they need loose moissanite; my friend said that this moissanite is very good in clarity and cut and is commendable in the entire global market. At the same time, I am very satisfied with their service. Once I joked that I like the oval Moissanite ring, they actually gave one, which is really unexpected!

It is really important to have a reliable supplier. AuGain Gem is one of them. We have been cooperating for 3 years. I mainly buy moissanite in DEF color here. Before purchasing from AuGainGem, I often encountered that I wanted DEF grade, but received HI grade or JK grade, which gave me a headache. Now I am very fortunate to work with AuGain Gem, every time it is true DEF grade, I no longer have to talk about the quality of the gems I buy, I recommended this AuGain Moissanite company to my friends.

I would like to say that my jewelry business has grown rapidly and I would like to thank not only our team, but also AuGain Gem. As our moissanite supplier, AuGainGem has been supplying us with reliable quality moissanite, which has made us praised by many consumers and accumulated a large number of loyal fans. This year, AuGain Gem has been supplying us with moissanite for 4 years, and we are very happy to cooperate.
