The details
Deep blue tanzanite takes center stage in this round gemstone ring, set with small diamond accents in bright sterling silver. The sterling silver is finished in rhodium, which gives a crisp, cool shine that lets the blue stand out. The round stone sits at the center with a diamond on each side of it, and the hollow build keeps the ring comfortable on the hand. Wear it with a soft gray sweater, or with a black dress for an evening out. It makes a lovely gift for someone born in December.

Jewelry care
- Sterling silver darkens naturally with air; the rhodium finish slows this down. A silver polishing cloth brings the shine back, and an airtight pouch keeps it there.
- Put jewelry on last, after lotion and perfume, and take it off before showering, swimming or sleeping.
- Store each piece on its own in a soft pouch so it doesn't scratch.
