This ring is sooooo nice! Very high quality, looks so real! The yellow is a very nice pale yellow and it SPARKLES. Such a good purchase for the price! Fits true to size for me and the 3.5 ct is a great size, not too big so it looks gaudy but really elegant!

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

    • It's so pretty!
Color: 7.0ct Ring Size: 7.5

The media could not be loaded. It's very pretty, but you can tell it's CZ. It's better made than most other CZ rings though (only found one other that's better than this one, an emerald cut CZ ring). It sparkles beautifully, but not as much as a diamond (obviously). If you're looking for an affordable alternative and don't mind it not being perfect, this is a great option. I almost kept it because it was very VERY tempting with how well made it is. But the ring size was a little too big for me even though I ordered my correct size. And the basket could be a bit sturdier as well if it was a lower profile basket, but it was a little too high off my finger for my liking. Added a comparison photo of a CZ Oval same mm stone size for reference. This one was better than the oval (just in case there was any wonder about it) ... show more

    • Disappointed with Ring
Color: 7.0ct Ring Size: 5
I’m returning this ring I was disappointed although it’s beautiful and this company does have great quality. The ring is a size 5 but it seems smaller on my finger. I have to tug a bit to get it off. That’s never happened before with this company. The center stone is not 7 ct it is much smaller. Normally, o order through tik tok not on Amazon. ... show more

This is straight out of the box, not worn at all yet. However, I will come back and update this review if it has bad wear. So far, this ring is gorgeous!!! I have had fantastic wear from this brand, and intend to repurchase/purchase new items. I would love to see this brand come out with more colored stone rings!! Value is high! ... 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
