  • Beautiful!!!, Protects real Ring and couldn’t spend money on a 6 carat ring!
Color: 6ct Radiant Cut Ring Size: 9
Love this AINUOSHI Brand of rings so much that I purchased 4 over time! Radiant cut, brilliant, cushion cut and princess cut. I have a real ring Princess 3 carat total weight but H/I color and no one can tell the difference in quality (only size) side by side...except for the ever slight tinge of warm color in my real stone. (One in box). And that’s only visible with microscope! I got them because of price and ability to change looks and because my ring has been sized twice and gets very tight and needed sizing and rhodium plating and service 2xs a year so wearing these in between, they give my real ring a rest and keep it from scratching up. and the thin bands and one size larger makes it fit better when fingers are swelling from temps, hormones and medication from being disabled. Nice cheap way to change out style! And all my close friends know what my real ring looks like... so no deceiving. A few bought them as there real ring in a 2 carat size! Just almost needed my real rings cut off...which was scary! I absolutely love them and no problems in quality or looks. I’m sure some people may think it’s to large for the average person but I’m 5’9” and wear heels! Not a small girl 172 lbs! Plus doesn’t hurt having other nice things I worked very hard for before my hubby got me a 3 carat ring. Saved like crazy for a nice , small custom built home w inground pool, always had used BMWs and Prada and Celine purses....makes no one question its believable. And all these things can be bought wholesale and pretty cheap/used if you take your time and search, if it’s what u love! We have never paid more than $10k for a used BMW or Mini Cooper. So thanks for a nice affordable, beautiful product for a “bargain shopper” like me! Trust me, I wouldn’t wear it if it looked like a big chunk of glass... but remember each one is individually cut and some are better than others! If you don’t like it, try another cut or size? They have 2-6 carat options from $25/$45. They may not be for everyone but Great investment for me! ... show more

  • OMG absolutely STUNNING!
Color: 5.5 Cushion Cut Ring Size: 7.5
Sparkly, gorgeous and thrilling! Stone is large enough to catch attention but not gaudy at all. It’s so pretty I almost don’t want to wear it because I don’t want to damage it! Just beautiful.

  • As close to a diamond as you will get.
Color: 5.5 Cushion Cut Ring Size: 10
The ring is really very pretty. It actually has the he sparkle of a real diamond and it fits true to the description. I have not worn it yet for any length of time but I’m hoping that the stones stay in their setting. It definitely was worth the price and it is a relief that I don’t have to wear actual diamonds when I’m out so this is a definite win. ... show more

  • Ring was half of a ring size too big
Color: 5.5 Cushion Cut Ring Size: 7.5
The media could not be loaded. I love the ring its beautiful, the only issue i have with it is that after measuring my finger with a ring sizer, we ordered the ring and it is half a size bigger than what it should be. My husband ordered a 7 and a half for me, and if i waved my hands around or got them wet it would fall off, i know i ordered the correct size for my finger because my ring that i wore for almost 5 years is a 7 and a half, it is the only finger on either of my hands that is that size. Conveniently they provied this plastic like spacer material and with that wrapped around the band of the ring it fits perfectly. Its decently comfortable with the spacer on it. I would have prefered not to have to wear a spacer on it, but it serves its purpose and makes my beautiful ring wearable without me being afraid of it falling off and losing it ... show more

  • AINUOSHI Engagement Ring, 5.5-6 CTW DEW, Cushion Cut / Radiant Cut, 925 Sterling Silver
Color: 5.5 Cushion Cut Ring Size: 6
Top quality CZ, beautifully cut, and perfectly mounted in a lovely sterling silver setting. It is also plated in expensive rhodium for a long lasting tarnish-free wear. Very believable & real looking. The fit is true to size. The sparkle is Out Of This World! Whenever I wear it, people stop me to look at my hand & compliment this ring. Nobody has ever guessed that it's not a real 5.5 CTW diamond, or that the setting isn't white or platinum. I love this ring as an engagement ring, or even as a right hand cocktail ring. You will never get this kind of sparkle from a real diamond of this size unless you spend tens of thousands of dollars --- so save your money to put down on a house, and wear this ring with pride & happiness! (Also a great ring for travel if you don't want to bring your real diamonds on the trip) Either way, I think this is a gorgeous stone, set perfectly in a sturdy yet feminine ring with smooth prongs..... and I am LOVING the #Romantic #BLING ! I highly recommend this seller if you are seeking top quality fine jewelry at the best price. :) ... show more

  • Gorgeous Gorgeous Gorgeous
Color: 5.5 Cushion Cut Ring Size: 10
Let me start off by saying this ring is freaking gorgeous!!! Like absolutely gorgeous!!!! Sadly I need to return it because it's too big. I saw a review that someone said it was a size bigger. I didn't listen because I have chubby sausage fingers. (sadly due to covid I've gained a few extra pounds which has made my real wedding ring really uncomfortable. My husband wanted to size my ringor get a whole new ring. I refuse since this is only temporary weight!! So I opted for a fake ring until my ring fits better. And shoot why not have a little fun and go a little bigger then my actual ring 😁 ) Well I should have listened to that review because now I have a ring that doesn't fit 😔 . So I showed my husband and cracked a joke thanking him for the new ring and of course I'd marry him AGAIN.. He thought it was too big and could possibly put myself in danger of getting robbed. I never considered that. I think its highly unlikely but you never know these days.. I have 6 kids and can be very oblivious to my surroundings while having my hands full. I'd never want to risk getting robbed over a fake ring!! So I will be downsizing to the 3 carts 😁 and downsizing to a smaller size. But please hear me when I say this ring is sooo freaking gorgeous!!!! 😫😍 ** Oh and I noticed it came with this little spiral thing. I couldn't figure it out at first. Probably because I was so in aww over the ring lol. But after I realized it's probably to clean any junk that might get stuck in-between the diamond. Very smart!! ... show more
