Rare Spanish Diamond Ring

A rare and striking example of late 17th-century Spanish jewellery, circa 1680-1700. This ring is crafted from high-karat gold (approximately 21-22K) and set with seven table-cut diamonds. The diamonds exhibit a distinctive gunmetal grey hue, achieved through silver foiling beneath the stones, an early technique that enhances their reflective quality.

The openwork floral design is an early precursor to the giardinetti (little garden) rings that swept through Europe in the 18th century, yet this example retains a more symmetrical, almost architectural form. Each diamond is set within a chiseled foliate setting, secured by clean rub-over collets, all in gold, a typical feature of Iberian jewels. The band is adorned with a finely twisted design. 

This ring is an excellent example of early Spanish nobility’s taste, where such intricate jewels were reserved for the wealthiest women of the time. 

It measures approximately 20mm in bezel diameter, with the central table-cut diamond measuring 2.5mm x 3.5mm. Weighing 4.6 grams, it is a UK size N (US size 6.75).

Condition: Excellent, with all diamonds securely set and the gold retaining its warm, rich hue, showing only light wear commensurate with age.

A magnificent and historically significant piece, this ring exemplifies the luxury and artistry of Spanish Renaissance jewellery.
