Great Customer Support

The guys were so great to work with. Was a very professional and easy process to design the ring with them, they gave plenty of help and support, and she absolutely loved it! Will definitely go back to get our wedding bands with them. Thanks again Jordan and Ben!

Easy Design Process

Jordan and his team did an incredible job helping with the design of this ring. The craftsmanship that went into creating this ring is impeccable, and I can tell it will last a lifetime. I can’t wait to the day that we start working on our wedding bands with Cullen Moissanite. I could not recommend this company more!

Ethical Australian Company

A HUGE thank you to everyone at Cullen Moissanite who helped make my 2 carat dreams come true. Both my fiance and I are beyond thrilled with not only the quality, but the price, communication and professionalism shown throughout all of our dealings with this remarkable company. If anyone is even considering purchasing from this wonderful Australian company I would highly suggest doing it, not only are you buying locally but also ethically.
