  • MUST HAVE
Color: 3.5ct(Yellow Diamond) Ring Size: 7
WOW! EXQUISITE attention to detail - AND A GREAT substitute for the price - let's be honest, we can't even wear jewelry in an ELEVATOR! SO why lose your WINSTON or Tiff. while you can enjoy this sophisticated piece without fear? LOVE your frosting!

  • Pleasantly surprised
Color: 3.5ct(Split Shank) Ring Size: 7
The media could not be loaded. I purchased the Size 7, it's beautiful, and comfortable on my finger. It's honestly so much prettier in person and shiny and all the sparkles too. This will be a great ring just when I'm feeling extra and on a night out. The gem is not overly sized in my opinion, but go big or go home right?! Spoil yourself and buy the ring! ... show more

  • DONT THINK JUST BUY!!
Color: 3.5ct(Yellow Diamond) Ring Size: 7
The media could not be loaded. Seriously though this ring is unimaginably Sparkly and photos and videos do not do it justice! I'm in love with this ring and it's 10000% better than the ring I have now. I cannot get over how pretty it is and have gotten nothing but compliments. I hardly ever write reviews but this absolutely deserves the praise. I did just get it so maybe I'll update this after some time has passed but we'll see. ... show more

  • Stunning
Color: 3.5ct(Split Shank) Ring Size: 8.5
This ring is absolutely gorgeous. Very modern. My only complaint is the center stone looks smaller then 3 karat but it’s beautiful

  • Pretty but way too big
Color: 3.5ct(7×10) Ring Size: 6.5
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.

  • 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

  • STUNNING KNOCKOUT OF A RING!
Color: 3.5ct(7×10) Ring Size: 7.5
The media could not be loaded. Wow! This gorgeous ring looks scarily like a real diamond! It has tons of fire (I couldn’t capture it well on my phone), but believe me, you’ll see it, too! Comfortable and easily nestled next to my diamond band, it is so attractive!! Love it and couldn’t be more thrilled—especially with this price point! ... show more
