Tanzanite and Diamond Three-Stone Band in Yellow Gold

This is a contemporary fine jewelry ring featuring three oval-cut faceted tanzanite gemstones set in a horizontal row across the top of the band. The tanzanites exhibit a characteristic violet-blue hue with moderate saturation and are likely approximately 0.25 to 0.40 carats each. Separating the tanzanites are four small round brilliant-cut diamonds, arranged in two vertical pairs, which serve as shimmering accents to the primary stones. The ring is constructed of yellow gold, likely 10k or 14k based on common commercial manufacturing standards. The setting style incorporates a shared-prong or bridge-style mounting that secures the stones while allowing light to enter from the sides. Notable markings described include an 'A/C' stamp on the interior shank, which likely refers to a manufacturer's hallmark or a specific collection identifier. The overall condition appears excellent with no visible gemstone chips or significant abrasions on the metal surface. The craftsmanship is consistent with mass-market fine jewelry from the late 20th to early 21st century, showing good symmetry and secure stone placement. The combination of violet tanzanite and yellow gold suggests a late 1990s or 2000s style period.
