In a favorite form of white jade amulet, the stone is cut flat and is then inlaid with rubies in gold settings, so disposed as to indicate a flower-form. Jade amulets of this type are found in China and in various parts of northern Asia, and are believed to guard or free the wearer from palpitation of the heart.[606] [Illustration: TIBETAN WOMAN WITH COMPLETE JEWELRY From “Notes on Turquois in the East,” by Berthold Laufer.

A celebrated beauty of London society has a number of pansies of different colors, one made of rubies, another of sapphires, still another of emeralds, and so on through the range of colors. In this way she always had a pansy according in color with that of her gown. As bridal gifts these jewel-flowers are most appropriate, more especially when the lady-love bears a “floral name” such as Violet or Rose. Coral ornaments of all sorts are in great demand in Tibet, and a fine piece of this material will bring about $20 an ounce, and is therefore literally worth its weight in gold. The Venetian traveller, Marco Polo, who visited Tibet in the latter half of the thirteenth century, already noted that coral was in high favor there and that coral necklaces adorned the necks of the women and also those of the idols in their temples. The love of personal adornment is very strong among the Tibetan women, and those in any way well-to-do load themselves with a mass of jewelled ornaments, great pieces of amber, coral and turquoise constituting the principal gem-material. The favor extended to coral, apart from the religious significance of red as symbolical of one of the incarnations of Buddha, may perhaps have an esthetic basis as well, for red or pink affords a pleasant contrast to the dark complexions and hair of the Tibetans.[607] Much more prized, however, than coral is the beautiful blue turquoise, which not only serves for purely ornamental use but is freely employed in the decoration of religious objects, such as the curious “prayer wheels” so indispensable a part of Tibetan ritual.
