  • My everyday earrings 5

    Posted by Valarie H. on Feb 13th 2023

    I wear these everyday and I love them. The shape and cut of the cushion cut is really spectacular compared to the real diamond round studs I used to have

  • Bought these as studs for a man (For me) 4

    Posted by Sean James on Apr 10th 2022

    I have round studs from Ziamond and wanted something different. I like this cushion cut shape and bought the 1.50 carat each size. They look really good and have a lot of shine. Ziamond is always more expensive but to be honest they are way better than any other cz place and even moissanites I have seen. Deducted one start because they could ship faster.

  • Best Christmas Gift I Received This Year 5

    Opened these on Christmas morning and have not taken them off since. They look amazing and I just adore the shape of the cushion cut.

  • Excellent product 5

    Posted by Richard James on Dec 19th 2021

    The quality of the merchandise was excellent. It was delivered in a beautiful, classy bow wrapped box. I was quoted 10 days delivery and it was here on my door step in 4. My girlfriend knows they are not real diamonds and thinks they are georgeous just the same. I rate this experience a 10.

    The quality of their products is fantastic. The only the I would improve is the processing and shipping times for orders. I would definitely buy from them again!
