Love this ring for my husband to be. It’s heavy and strong which is perfect for him to wear to work. The blue addition to the ring is sublime, It shines perfectly against the brushed black Tungsten metal. Perfection. Thank you MR for such beautiful creations.

Purchased a ring 2 ywars ago for our wedding. Was beautifully crafted and hubby said if felt great to wear. Fast forward 2 years and its now too big for his finger and he keeps loosing it. We were able to get it replaced with the same ring in a better size with so much ease. The correspondence was amazing, friendly and personalised to our needs. So easy to do and cannot fault them at all.

Perfect ring! Great quality, so much better than the picture. Feels nice and heavy and smooth to wear. Beats buying in the store and paying way more - loved it more than the ones in the store anyway. Had to send back to get a different size - they were very helpful and the second time the fit was perfect.
