The most interesting and perhaps the best-known French peasant jewellery is that of Normandy and the Auvergne. The chief Norman jewel is the cross. The most usual form is that which occurs in the districts round St. Lô and Caen. It is of silver, formed of five high bosses, four round and one pear-shaped, each set with a large foiled rock crystal (commonly known as _Diamant_, _Caillou_, or _Pierre d' Alençon_) cut and faceted in the brilliant shape, and further ornamented with sprays set with small crystals in rose form. The lower limb of the cross, _briolette_ or pear-shaped, is hinged, so as to render it less liable to get bent or broken in wear (Pl. LIII, 4). The spaces between the limbs are sometimes completely filled up with branched open-work set with small crystals. In the more northerly parts of France the cross is formed simply of large bosses set with crystals; but round about Rouen we meet with an abundance of spray-work. Other crosses of considerable size are formed of thin plates of pierced gold. The shape of the cross is indicated simply by crystal bosses, but its form is almost lost in the outline of the jewel. A favourite subject for representation on Rouennais jewellery is the _Saint Esprit_ or Holy Dove. Employed as a breast-ornament or pendant, the Dove is either in gold or silver, mounted with crystals, or coloured pastes set close together. It is suspended from an ornament of open knot design, with a rosette-shaped slide above. In its beak is a branch, spray, or bunch of grapes, generally of coloured pastes. Peasant jewellery ceased to be worn in Normandy about 1840, when native costume was given up. While Normandy relies chiefly on crystal quartz for its jewellery, the Auvergne can boast of a variety of gems, such as garnets, opals, spinels, and zircons, which are of frequent occurrence in the volcanic rock of Central France. The jewellery of Puy is mounted with cabochon stones in large high settings. Open-work circular pendants have a central boss with eight similar settings around. The _Saint Esprit_ is also a popular jewel, but in these parts the form of the Dove is not completely carried out, the jewel being composed merely of five pear-shaped bosses to indicate the wings, body, head, and tail of the bird.
