A pink chalcedony shows off its beauty. Chalcedonies include many types of cryptocrystalline quartz gems and feature a number of different colors. Geologists can tell a chalcedony from the arrangement and structure of its crystals.
意译：矿物的图片集。一个粉红色的玉髓显示它的美。玉髓包括很多类型的隐晶的石英宝石和具有不同的颜色。地质学者能够说明玉髓来自结晶的排列和构造。

Azurite crystals from Arizona seem to pulse with color. The mineral azurite—a copper ore—consists of blue basic carbonate. Azurite's brilliant color adds to its popularity in creating semiprecious stones.
意译：矿物的图片集。蓝铜矿的结晶来自亚利桑那州好像添加彩色。兰铜矿是以铜矿石组成为蓝色基本的碳酸盐。兰铜矿灿烂的色彩加上它的声望造成准宝石的宝石。

Mineral deposits in Lechuguilla Cave take on fantastical forms in Carlsbad Caverns National Park, New Mexico. Stalactites of calcite and a small aragonite formation appear as if in a magical backdrop. Calcite and aragonite are the two crystal forms of calcium carbonate, a property of minerals geologists call dimorphism. Their crystal structure sets them apart: calcite forms hexagons and aragonite forms rhombohedrons.
意译：矿物的图片集。矿物沉淀物在墨西哥龙舌兰洞穴位于卡尔巨洞国家公园，新墨西哥。钟乳石的方解石和一小的文石组成似乎像一不可思议的背景。方解石和文石是两种碳酸钙结晶组成，地质学者称二态性。它们的结晶构造使它们分离：方解石型六角形和文石的菱面体。
