    • Beautiful ring. Love! Great price!

Review Image by Learning In Texas
This ring is gorgeous. I got it as a gift and it really made me elated with joy! It is comfortable to wear. And people think it’s a diamond. I don’t lie. I just smile. I don’t care for real diamonds. I think they cause a lot of trouble in this world. However I do love their shine and sparkle. This ring is a winner. It’s very big and can make one feel out of place wearing it. But really who cares! We all deserve to wear things we like regardless if we would drop 10k on a ring or not. I personally would not. I have a nice video of it’s sparkle, but Amazon would not upload the 9 second video for some unknown reason. ... show more

    • Holy moly!! This ring!
Color: 3.5ct Ring Size: 7
Just like any other person on here; I purchased this ring as a temporary ring because i am about to go on a trip and didn’t want to risk anything happening to my real diamonds. Now I didn’t have a lot of hopes because it was just a decoy ring so I didn’t care much about it but I am going to be gone for a few weeks and I didn’t want to purchase a $10 dollar ring and having it turn green mid trip lol so I read the reviews on this one and the ring looked stunning 🤩 but again I didn’t expect much. Upon receiving this ring, my mind is blown away!!! The shine and sparkle on this ring is insane!! I am absolutely shocked how real this looks and how beautiful it is!! I placed my real diamonds next to this ring and I couldn’t tell the difference. I highly recommend this to anyone going on trips an want to leave your real diamonds home or even if you want a more inexpensive alternative to an engagement ring!!! Honestly it’s so beautiful I nights wear this instead lol ... show more

    • Buy it now! Don’t think twice about it!
Color: 3.5ct Ring Size: 6
Top ring is:(Effinny) Bottom ring is:(My wedding ring) I got this ring for traveling, but I was scared because of the bad reviews on here.. yeah.. I’m happy I didn’t listen to the bad reviews! I AM LEFT SPEECHLESS! This ring looks like my real ring! I’m definitely going to wear it out on my other hand! It’s way waayyy too gorgeous not to wear it! 😍 (side note: I believe the bad reviews are because people don’t know how to take care of cubic zirconias.. Just try your best to not get it wet, keep away from other jewelry, try not to bump your hand on anything or do anything that can scratch or break it and it’ll last you!) ... show more

I ordered this ring because I got engaged right before an international trip and I panicked and couldn't decide if I wanted to wear my real ring or not. I ended up wearing my real one, so I'm returning the ones I bought for this purpose. This ring is pretty, but you can tell it's not a real diamond by the "crushed ice" look. I also ordered the smallest size, which was 4.5, and it was a little too big on me, which was a shame. In the picture with two rings, this ring is on top, and my real ring is on the bottom. It comes in a nice box with a cleaning cloth and pouch to carry the ring box in, which is a nice touch. Overall, if it had fit, it would make for a good travel ring, but not for everyday wear. ... show more

Absolutely BREATHTAKING…. I am left speechless. As someone who is GIA certified, I find it hard to convince anyone to buy a mine nor a lab grown diamond when simulated diamonds are this good. It speaks for itself. Video files were too big to post but man is the cut absolutely incredible, I’ve never seen a radiant sparkle quite like this. No bow tie in the middle either ... show more

Extremely disappointed. I mean, yes it’s an under $70 ring but geeeesh - seriously? Does no one check the items before mail them out? I received today, I was extremely excited until I open a clearly already opened box. The sizing label was broke off the ring. The ring doesn’t have a shape it was obviously wore and altered. The main big “diamond” have zero spark, no spark whatsoever, none. Very cloudy and heavily scratched. To top it off not only have one of the little “diamonds” in the band missing but two! Two diamonds missing on the band. The main “rock” besides being cloudy and dirty was also very very scratched. Very sad purchase. Off it goes to get returned asap! ... show more

Comfortable, but 3.5 ct looked ridiculous. Obviously a fake ring. Setting was high off the finger. It was sparkly and pretty but I felt silly. My kids said it was too big.

    • Very radiant
Color: 3.5ct Ring Size: 8
This is an absolutely stunning ring. It is not emerald, cushion, or princess cut but a rectangle with strategic cuts to enhance randiance. It is a bit taller than I imagined it would be. There are stones on the setting framing the main stone and also down the band itself. The stones on the band are not bothersome to my other fingers as some rings with stones on bands are. The ring came earlier than expected, in a nice box and was true to size. As for passing a diamond test on a tester, I've not taken it in and had it tested. I will update my findings. ... show more
