    • Stunning. Absolutely stunning.

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

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!

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

I ordered this in February and have worn every day and is now 6 months later. It hasn’t turned but 3 stones have fallen out. I would not purchase this again. I have to find something else to replace it. The main stone always looks cloudy even after you clean it.

    • uh
I have now had this ring just shy of a year. It looks nothing like the picture, I still like it BUT the only rose gold part left it the part around the "diamond"

    • Exactly as pictured, stone leans a darker yellow
Color: 3.5ct(Yellow Diamond) Ring Size: 6.5
Exactly as pictured. Stone leans a darker yellow, not cool like lemon yellow or creamy like buttercup. Is sparklingly clear, edges are smooth and doesnt pick at clothing, band is smooth, maybe 2-3mm
