Sfera Blu Ring is a delicate, modern piece crafted as part of Calvéra’s exclusive Blue Duo Collection. Designed as the first half of a two-ring ensemble, this slim gold band is crowned with a polished round golden base holding a radiant blue orb. Soft, luminous, and expressive, the blue sphere adds a vibrant pop of color that makes the ring instantly captivating.

What makes Sfera Blu truly unique is that it is meant to be worn exclusively with its companion ring, the Arco Blu Ring, which features a golden horseshoe-shaped design. When worn together, the blue sphere fits perfectly inside the horseshoe arc, creating a unified, artistic composition — two rings forming one harmonious piece.

Crafted from premium stainless steel and finished with advanced gold-plating for long-lasting brilliance and lifetime color stability — fully covered by Calvéra’s 5-year warranty, Sfera Blu Ring maintains its glow and vibrant charm through years of wear.

A playful yet refined design, Sfera Blu Ring celebrates connection, balance, and the beauty of pieces that are made to complete one another.
