Dr. Kwan Siu Yee will officiate at the opening ceremony. The exhibition will be on until 26th March. Archaeological discoveries have revealed that natural mineral rocks were used as ornaments or worn as amulets by our remote ancestors p r i or to the emergence of civilizations. As early as the Paleolithic period, the Chinese already made use of quartz, rock crystal, flint, and opal to produce a variety of implements. By the Neolithic times, stone materials were more widely used. Since quartz is the commonest rock-forming mineral, ancient lithic tools and stone carvings made from quartz materials largely outnumbered those of jade. Quartz, its main constituent being silicate dioxide, is widely distributed on the earth's crust. The presence of different kinds of transitional elements and impurities in crystalline quartz has given rise to a wide range of semi-precious gems such as citrine, tea quartz, smoky quartz, and amethyst. Some with inclusions of hair-like filaments are called hair-quartz. Agate and chalcedony fall into the group of microcrystals. The majority are white but different colours may occur due to the presence of transitional elements and impurities. Layers, bands, and grain patterns of different colours may configure to give an extremely resplendent visual effect. Names of sardonyx, onyx, moss agate, and banded agate have been used to represent different configurations. Over 200 pieces of rock crystals and agates from the Neolithic period to the Ming dynasty, all from the Taoshi Zhai Co l l ec t i on w i l l be featured in the exhibition. The great variety of tools, adornments, utensils, pendants, plaques, and miniature animals demonstrate the distinguished accomplishment of the ancient Chinese carvers in these two lithic media through the millenniums. The collector, Mr. Roger Chow, will give a talk on ancient Chinese rock crystal and agate carvings at 2.30 p.m. on 22nd January at Room 126, Institute of Chinese Studies.
