1. 什么石萤石？

2. 萤石都有什么颜色？

萤石最常见的颜色可能是无色或紫色，最罕见的颜色是粉红色，这是典型的只有在法国，瑞士和巴基斯坦阿尔卑斯风格的裂缝。粉红色萤石的标本可能很值钱。

3. 各大颜色艳丽的为值钱的矿物标本

在美国中西部贱金属矿的巨大洞穴中发现了宽度超过一米的晶体。美国和中国的一些矿山可能已经生产了数十万个萤石的精细标本。在全世界数千个地方都有发现。历史上，许多萤石标本都来自西欧，主要来自英国、法国、西班牙和德国，它们是从开采热液矿脉的矿山中采集的。西班牙生产的萤石在欧洲任何国家中都是最多的，无论是矿石还是标本，其中大部分产自阿斯图里亚斯。这些矿山开采石灰石中矿化的萤石，生产出紫色、蓝色、黄色或无色的立方体样品。世界上最大的萤石标本来自美国中西部，与大多数最好的矿点一样，这些地方都是沉积岩。在伊利诺伊州南部的塌陷岩石周围发现了直径达一米的立方体。伊利诺伊州的萤石以其引人注目的分带性而闻名，已知的标本在同一片中显示出明亮的黄色和深紫色。

4. 工业用途：
萤石被开采为化学工业的氟源和工业钢铁制造的助焊剂。

5. 赋存在哪里？

萤石是一种非常常见的副矿物，存在于地球上大多数地质环境中。它最常见于热液脉中的方解石、石英、黄铁矿、方铅矿、黄铜矿和/或白云石，但也可在各种其他环境中发现，如泡状玄武岩、溶洞状白云岩、伟晶岩、糜棱岩、云英岩和矽卡岩，通常与铜、铅、铁、银等金属矿石伴生，钨、锡和金。除了这里讨论的热液脉，在花岗岩、阿尔卑斯山或云英岩矿床中也发现了许多细萤石。萤石通常生长在阿尔卑斯山的裂隙中，在溶蚀花岗岩的岩洞壁上，以及在含有锡石和白钨矿的矿脉中。产生此类矿化的良好例子的地点有德国Zinwald、捷克共和国（Greisen）、美国新罕布什尔州（Miarolysic granite）和法国勃朗峰（Mont Blanc，阿尔卑斯裂缝）。
