The Sfera silver ring features a 7 × 7 mm spherical motif whose surface is entirely covered in Czech garnets. Czech garnet is prized for its deep, fiery red colour, which sparkles from every side on the rounded surface of the sphere.

The ring is made of rhodium-plated 925 silver. The rhodium layer protects the silver against oxidation and tarnishing and gives it a bright, long-lasting shine.

You will find it in our range of rings and in our pearl jewellery category.

A certificate of authenticity for the Czech garnet is included.
