Uno de 50 Core Blue Stone Statement Ring

That specific shade of blue — saturated, grounded, neither navy nor turquoise — is what makes this Uno de 50 blue stone ring stop you mid-scroll. The Madrid-based artisanal jewelry house has built its reputation on pieces that feel intentional rather than decorative, and the Core Blue Stone Statement Ring is a clear example of that philosophy. The stone is the point: boldly set, structurally confident, and scaled to be noticed without needing anything else on the hand to justify it. If you gravitate toward jewelry that carries its own weight, this one is built for you.

Uno de 50 works in small batches with handcrafted techniques — a practice that shows in the finish and the way no two pieces are quite identical. The ring sits in that sweet spot between everyday wearable and something you reach for when you want to make a quiet statement.

• Bold blue stone centerpiece in a structured, elevated setting
• Handcrafted by Uno de 50 artisans in Madrid using small-batch production methods
• Silver-toned metal band with the brand's characteristic textured detailing
• Designed as a statement piece — scaled to be worn solo or as a dominant stacking anchor
• Part of the Core collection, reflecting Uno de 50's signature approach to wearable sculptural jewelry
• Finished with the quality control standards the brand has maintained across decades of artisanal production

To keep your Uno de 50 blue stone statement ring looking its best, avoid prolonged exposure to water, perfume, lotions, and cleaning products — these can dull the metal finish and affect the stone's surface over time. When you're not wearing it, store it separately in a soft pouch or lined jewelry box to prevent scratching from contact with other pieces. For cleaning, a dry or very lightly dampened soft cloth is all you need; skip ultrasonic cleaners and harsh chemical solutions entirely. Treated with that basic care, this Uno de 50 artisanal ring will hold its color and finish across years of regular wear.
