Amazon Prime Membership TI SENTO Ring 12066ZI. The exclusive TI SENTO ring is fabricated from rhodium plated sterling silver, with the rhodium giving the jewellery added shine and durability. The ring's unique design is formed with several bands of smooth silver, with black oxidation and silver accentuating the pattern alongside the brilliance of cut CZ to add sparkle. This is an extremely comfortable ring to wear, as the inner imprint ensures absolutely zero constriction.
