A rare mid-19th-century Venetian spherical container, crafted to hold a single precious coin, originally intended for a now-lost Byzantine coin. The piece is formed from two transparent solid crystal spheres that open to reveal a deep circular recess carved into the lower half, designed to securely house the coin.

The central opening is encircled by a double band of gilded 800 silver, exquisitely decorated with finely executed hand engravings. The opening and closing mechanism is integrated into this elegant silver mount.

A remarkable example of 19th-century Italian craftsmanship, combining refined artistry with exceptional rarity.
