Received our 'Taken' rings from Rock Solid and his and hers. They are stunning, we are thrilled with them! The rings are such high quality and so well made, I needed to exchange my original one for a size smaller. Paul was fantastic and highly efficient. It was easy to exchange for the right size. Highly recommend, will definitely order some others in the future. Thank you! G&C

I love my ring so much. Your customer service was great about exchanging it for a bigger size. I’ll definitely use your company again and people have complimented asked where I got my ring so you have been recommended by me. Thanks again. 😊

Customer photo review of The Black Opal 8mm Wonder Ring

Ordered my ring, came the next day, but when measuring I hadn’t taken into account the wide band (makes them smaller!), so I emailed to explain my issue and without any hesitation they sent the next size up out for me straight away, with a pre paid envelope to return the original ring. Absolute gold customer service! I’m going to order a smaller silver one so I can wear with my other rings too. Such amazing quality and great customer service. 10/10

Absolutely gorgeous ring! Wife is so happy with it! The little sparkles of pinks/greens/blues catches the light and shimmer so beautifully! Unfortunately I ordered the wrong size, however, after a quick email to Paul, he arranged for the ring to be exchanged at no extra cost which was amazing and done so quickly! I would 100% recommend and will definitely purchase from here again ☺️

The Black Opal 8mm Wonder Ring

Customer photo review of The Black Opal 4mm Wonder Ring

These have been an amazing company to do business with; Picture shown is a 4mm and 8mm identical rings. Just note the 8mm is thicker than you think; we messed up an order and they jumped straight on it and got us the right ring. The only downside was how the shopping basket worked which caused a little confusion, when we tried to delete the items it kept sending emails which confused us a little and made us doubt that we orders the right ones. Return of the incorrect the rings was perfect and couldn’t ask for a better service

Customer photo review of The Black Opal 8mm Wonder Ring

Ring looks really great & I'm very happy with it. What I'm even more impressed with is the friendly, quick and easy way I was able to change the version I initially received for a smaller size due to my inept initial measuring. An excellent company and I will definitely be using them again. Highly recommended to everyone

Nice bit of kit for a 24th wedding anniversary. Discreet and stylish, not garish like some of the others on the market. Quick delivery, excellent packaging and seems really well made.
