This stunning, one-of-a-kind piece features a teal, oval-cut American Montana sapphire that is fit for a mermaid. Set in gold, the setting is hand carved specially for this brilliant cut blue-green gemstone.

I took inspiration from undersea worlds when designing this piece. It would make an amazing engagement ring or anniversary present to symbolize an everlasting love that goes deeper than the ocean.

    A Perfect Engagement Ring

    I purchased the Ceto Solitaire as an engagement ring and couldn't be happier with it. I'd originally been considering a few other different rings from Valley Rose, and thought stacking them with one of a few simpler rings as a wedding band could look nice. Brittany was both incredibly helpful with suggestions and sent along photos of the different pairings so I could see each different set together. When the time came to purchase rings, Brittany was even able to help me get a hold of the last one available at the time. Crisis averted! If you're considering a Valley Rose piece, trust that they're fantastic.
