Tiffany & Co. No-Heat Pink Sapphire Diamond Three-Stone Ring, 3.57 Carats

This three-stone ring from Tiffany & Co. features a 3.57-carat pink sapphire center stone with no heat treatment, paired with diamond accents in the setting.

The ring exemplifies Tiffany's characteristic design approach to precious gemstone jewelry.
