摘要

Is there a gemstone inside some bamboo stalks? Not exactly, but there is a gemstone relative, known as tabasheer. It is an amorphous (without crystal form) hydrated silica, just as all opals are. It occurs naturally in some bamboos, either in the nodes or, most commonly, within the internodes. The presence of a silica mineral should not really be surprising, since most bamboos are known to have a high silica content, According to Kunz (1915), tabasheer ranges from translucent to opaque, is white or bluish-white by reflected light and pale yellow or slight cherry red by transmitted light. It has some curious characteristics: if touched to the tongue, it adheres strongly; if put into water it emits rapid streams of minute bubbles; it absorbs large quantities of fluid. The specific gravity is 1.93, appreciably less than that of common opal, according to Farrelly (1984). Measuring the specific gravity takes a bit of work, because tabasheer has a large -volume of very small pores, from which air must be displaced to get a true reading, When the air is completely displaced, the material frequently becomes translucent.
