We got these as our wedding rings. This one is very study, well made and it looks awesome! It looks like a black band from a distance but all the flecks of red and orange really show from close up! Perfect blend of subtle and cool for my new hubby

I loved it. I got this as a gift for my fiancé so he can walk around wearing my birthstone and he wears it every single day. The seller even included and cute note thanking me for supporting them. Definitely recommend!

We needed to return the ring (our fault in sizing!) and Matt was so helpful and gracious. The ring, while it didn’t fit (again, MY error) was stunning, absolutely beautiful. A++ quality. We can’t wait for the new ring to get back to us!

Charlie

Great ring which was made easy by a great Dude. Thanks Matt!

⭐⭐⭐⭐⭐
Neal

Looks almost exactly like the photo. The 6mm version I purchased has just enough heft to make an excellent thumb ring, and sits nicely. The garnets inside are not set flush with each other, so you get a wonderful color change as you look along the ring.

⭐⭐⭐⭐⭐

Quality seems good, looks like it did in the picture, it's a lot more green than blue but it depends on from which direction the light comes from. Yeah so I'm happy with the purchase. Would recommend it.

The ring is gorgeous, and the customer service is amazing. I bought this for my boyfriend, originally I had ordered it in the wrong measurement, so it came too large. I contacted the seller about it and they gave me a new resized one for free, they were so kind and helpful and the exchange process was really easy and quick, The ring looks beautiful in person, just like the pictures and my boyfriend loved it, would highly recommend!
