  • Compliments galore!
Color: 3.5ct(7×10) Ring Size: 6
Absolutely love this ring. I actually wear this instead of my real bands and engagement ring; mainly because I gained weight after getting pregnant so this was a cheap quick solution. I wear this daily and get so many compliments. Due to wearing it daily, it does get dirty and cloudy so I clean it and it's back to shiny new. ... show more

  • Holy moly!! This ring!
Color: 3.5ct(7×10) 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

  • My favorite
Color: 7.0ct(9×13) Ring Size: 5
I love this ring and I get so many compliments. It truly looks high quality. It gets dirty really easily so I’m constantly washing it so that it doesn’t look foggy.

  • It's so pretty!
Color: 7.0ct(9×13) 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

  • Not too shabby! A little heavy for the band!
Color: 7.0ct(9×13) Ring Size: 7.5
The media could not be loaded. Love the clarity definitely don’t get her wet though, make an attempt at not knocking the stone into anything or being too rough while wearing it, and it should last you quite a while! Buying jewelry cleaning products is always recommended when owning pieces like this that are false diamonds but genuine sterling silver as the iron in skin secretions can still tarnish the metal. If you are anemic I would suggest placing a clear coat of polish on the inner lining of your ring to help save it from damage! Over all it’s gorgeous, a little pricier than I had hoped but, beautiful, and definitely a show stopper! I would suggest it as a gift for yourself or for someone else, but keep in mind it isn’t real so the tarnish time is much sooner than you’d think. As long as you’re ok with that she’s GORGEOUS! ... show more
