Art Nouveau Banded Agate Shield Signet Ring in 10ct Gold

A powerful and characterful signet ring, c.1920, crafted in 10ct yellow gold. The ring features a broad shield-shaped table set with a hand-carved banded agate. The stone displays a deep, translucent chocolate-brown hue, bisected by a striking, singular white horizontal band.

The gold mounting is distinguished by its ornate, high-relief scrolled shoulders, typical of the late Art Nouveau aesthetic. With a substantial weight of nearly 9g and a bold 20mm face, this ring offers a significant presence on the hand. A timeless piece of historical "armour" for the modern wardrobe, it remains in excellent vintage condition with clear '10k' markings.
