  • In love with this ring!
This ring is gorgeous! The detailing is beautiful and it looks like a far more expensive ring. My husbands weight..and thus his ring size.. has fluctuated a lot over the years. The ring he has been wearing for the past few years is now too big, so I needed to get him another one since he no longer likes the really old one that does fit him currently (I hope that makes sense). The inside of the ring feels really nice on and fits very comfortably. My husband commented on it's weight. His current ring is a silver one and is very lightweight, but this one has a nice, sturdy feel to it and he really likes that about it. His ancestry is irish and he has always been fascinated (ahem, obsessed) with anything irish or celtic. I feel like the design on this ring shows that heritage without being flashy or looking cheap. It has a wedding band look to it. I kind of wish I could find a women's version for myself, especially since I've been doing my own family history the past few months and have discovered I have a lot more irish in me. :) I think I'm going to order a couple more of these rings in different sizes so that as my husbands hands change he can keep wearing the "same" ring. I will try to share photos tomorrow. I didn't get a chance to take any pictures before he went to bed and he insisted on wearing his new ring. :) I was able to get this ring at a discount in exchange for my honest review. This does not affect the review that I leave, though. I really am blown away by how nice this ring is! ... show more

  • Amazing ring!
Looks amazing, especially in the light, where the colors really show; but you can still see glittering colors even in lower light situations. Highly durable (I've bumped it, dropped it, etc., and it's still barely showing any signs of wear). Pretty comfortable too; I had bought a half-size too big, and since they're so affordable, I just bought a half-size down a few weeks ago, and it feels much better! It's a big bulky, but if you have big hands, it doesn't really get too uncomfortable until bedtime (and I'm unused to wearing rings, so it might just be me). This is definitely more of a masculine ring, as it's pretty wide and has a good size and heft to it; it could also look really good on women with larger hands. Will be recommending these to any of my friends getting married! ... show more

  • Impressive ring, at a great price!
Color: Black with Green Color Stones Ring Size: 7.5
I have purchased several Tungsten Carbide rings on Amazon.com over the years. Most have been great, but some of the gold and rose gold rings by other sellers looks a bit dark due to the dark gray hue of the underlying Tungsten metal. This beautifully crafted ring appears just the opposite! It has a bright copper/gold appearance, and does not look cheap at all. The zodiac symbols are small and understated, someone would have to look closely at your finger to really see them (which I personally like). I wear this ring along with some of my expensive rose gold accented watches and it matches great, giving a custom designed look. A coworker asked where he could go, to have this ring custom designed for his wedding band and when I told him I bought it at a such a great price on Amazon.com he couldn't believe it! If you're into Astrology and on a budget, this might make a great wedding band (or travel ring). No one will think it's a cheap piece of junk jewelry. Just be careful, as Tungsten Carbide tends to shatter if you drop it against a hard surface. ... show more

  • Pictures don’t do it enough justice
This ring is beautiful and well-made. I can’t seem to get a photo that captures the true beauty and sparkle of this ring, but in bright light it looks amazing! It seems like it will last a long time and I’m very happy with the fit!

  • Beautiful ring!
Color: Blue Color Stones 4mm Ring Size: 12
This ring is absolutely beautiful. I bought it as an engagement ring for my now husband three years ago. Unfortunately it snapped in half a few days ago and he is devastated. He works hard and plays hard, I pleased with how well it held up but disappointed that it snapped in half. Ihope we can get a replacement for him soon. ... show more

  • Lovely rings, great customer service
I got these rings as a set for my fiance and me. His is perfect, but mine had some defects on the surface. I contacted the seller and Jasmine was extremely helpful and willing to work with me to find a solution. I was able to get the ring replaced easily and quickly. The replacement is flawless and absolutely lovely. The rings are true to size, and feel great to wear. I'll add pictures when the rings get used in a few months! Thank you again, Jasmine! You're awesome! ... show more

  • Nice ring!
Very pleased with this one compared to my last one. Actually had 2 of the others, and they were just too dark. This one is bright and very colorful.
