集骨石:这是一种放射状硅质框架的构造石。原岩经过千万年的自然风化,软质矿物渐渐销蚀,遗留下相对硬度大的放射状框架,看上去像是许多骨头集中在一起,因此叫做集骨石。形态完好的集骨石如同开放的菊花,有些石友称其为“风成菊”。白色的集骨石则看起来更像吃剩的鸡骨头,因此又有“鸡骨石”之名。此种石头能出主题、形态明确的不多,一般是赏其瘦骨嶙岣的结构和参差交错的天然肌理,若形如花团锦簇则非常引人入胜。玛瑙或玉髓质地者具有更高的观赏价值和经济价值。
Set of bone stone: This is a radial siliceous frame structure stone. The original rock after thousands of years of natural weathering, soft minerals gradually eroded, leaving the relative hardness of the radial framework, looks like a lot of bones together, so called set of stone. Shape intact set of stone like an open chrysanthemum, some rock friends call it “wind into daisy.” The white set of bone stone looks more like leftover chicken bones, so there is “chicken bone” name. This kind of stone can be the subject, the shape is not much clear, usually to appreciate the structure of its skinny and staggered natural texture, if the form of flowers is very fascinating. Onyx or chalcedony texture has a higher ornamental value and economic value.
