I recently purchased this lovely silver sapphire ring. I’m am really impressed with the quality and the design which I was customised for me. I wear my ring everyday as it’s light weight, not heavy and has a nice subtle sparkle.
Selena designed and made a truly stunning sapphire ring for my friend. She was responsive, helpful and an absolute delight to deal with. The craftsmanship is beautiful and the whole experience was seamless. I couldn’t recommend the Sapphire Theory more highly.

This is my fifth purchase from The Sapphire Theory. Each was a dream ring. Georgous stone, organic style, infinitely wearable, unique and ultimate heirlooms if you can pry them off my cold dead hands.

I had been eyeing this piece off for so long and finally decided to get it as a 30th present to myself. I wear this ring every single day and (other than my engagement ring 😆) is my absolute favourite piece of jewellery that I own. I always get compliments on it!
