French table-cut diamond cluster ring c.1780

DESCRIPTION

This charming French cluster ring, circa 1780, is crafted from silver and 18k solid gold, set with nine table-cut diamonds.

As the hardest mineral on the Mohs scale, diamonds can only be cut using other diamonds. In an era when mining was difficult and industrial cutting tools were unavailable, the angles and symmetry achievable in diamond cutting were quite limited. The table-cut was one of the earliest cutting styles used in jewelry, following the natural octahedral shape of diamonds. This ancient cut dates back to the Middle Ages and was particularly popular during the 17th and 18th centuries. Its characteristic beveled square corners and large, flat top, resembling a table, gave it its name.

The ring's design takes the form of a cluster, with smaller diamonds surrounding the central diamond to highlight it visually. All the diamonds are table-cut and set using an ancient bezel-setting technique, where the metal is rubbed and extended over the diamonds. The craftsmanship is rich and ornate, strongly conveying a unique charm.

The piece is in good antique condition, showing normal signs of oxidation and wear, with visible traces of resizing on the shank.
