It is composed in high-karat gold and set with a central rose cut diamond surrounded by 14 deep green table-cut emeralds in cut-down collet settings. \u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eThe vivid green emeralds are Colombian in origin, and their abundance is characteristic of Spanish Iberian work of this period; Spain's colonial control of the Colombian and Peruvian mines in the 17th century meant that emeralds became a defining feature of Iberian court jewellery. This piece exemplifies that tradition, with a striking radial symmetry that evokes the sunbursts and floral forms so typical of the Baroque.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eThe cluster is backed with foil, enhancing the stones’ depth and brilliance, and mounted on a fluted, enamelled gallery: black enamel inlay fills the deeply grooved underside, punctuated with tiny white dots - a highly specific form of decorative treatment seen in Western European jewels of the second half of the 17th century.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eThe shoulders continue the ornate detailing, chased with stylised flame or foliate motifs and delicately inlaid with black enamel.
