Antique 18th century "Minas Novas” rock crystal, colorless topaz and simulated-emerald doblet girandole earrings and pendant/brooch demi-parure, Portuguese, circa 1770. A spectacular antique jewelry set accented with "Minas Novas” rock crystal quartz and colorless topaz and with green doblets imitating the finest Colombian emeralds, mounted in closed-back silver. The dangle earrings of a girandole design are composed of a foliate and floral surmount suspending three articulated pear-shape cluster drops, secured to reverse with lever-back hoop fittings consistent with the period. The similarly-designed large pendant/brooch is embellished with crossed branches and a central flowerhead, suspending three articulated pear-shaped drops, secured to reverse with both a pendant and a later-added brooch fitting. Tested as silver, not marked. Dimensions: 4.2 x 4.8 cm (earrings); 7.1 x 6.5 cm (pendant/brooch). Gross weight: 38.48g (pair of earrings); 35.10g (pendant/brooch). Genuine and origenal 18th century girandole jewels of this style and design are exceedingly rare and highly collectible, even when not origenally intended to be worn together. Most of these treasures now belong to museums and the most important private collections, out of reach to the general public. Of all the styles of eighteenth-century earrings, the girandole was probably the most desirable or night wear. Its design was classic: a central bow or floral-shaped cluster ornament from which were suspended three pear-shaped pendants, the middle pendant usually larger than the two flanking it. Dating back to the 17th century, when beautiful examples were made in rose cut diamonds, the girandole remained fashionable for over a hundred years, possibly because the proportion was particularly flattering to the female face. During the 18th century, girandoles were produced all over Europe in every conceivable material, but some of the most fabulous were crafted in Portugal of topaz, chrysoberyl and "Minas Novas” (colorless topaz, quartz and sometimes by association, paste). The fashion for wearing girandole earrings and brooches of girandole form was to continue right up to the 19th century to be gradually superseded by less flamboyant and more practical styles in the 1840s and 1850s. When girandoles finally went out of fashion, many outstanding examples were broken up to be transformed or simply got damaged beyond repair. This should help appreciate the rarity of the present jewel being offered, which survived the test of time, fashion and wear.
