矿物拍卖（地球宝藏）

这件标本来自昆士兰的砾岩蛋白石，由一个三角形的铁英石碎片组成，其裂缝被胶结后填充了珍贵的蛋白石涂层，在这件标本上可以清晰欣赏到这薄而鲜艳的薄层，拥有出色的多彩针火彩，在手中旋转时会变化并闪耀。未加工状态的这种材料很少见，因为大多数都会被加工成珠宝，坦率地说，从经济角度来看更具收益。

This piece features a beautiful specimen of boulder opal from Queensland, consisting of a triangular ironstone fragment with cemented fractures that were filled with precious opal coatings, which are easily appreciated on this specimen as thin brightly colored pellicles with excellent multicolor pinfire that changes and sparkles when rotated in the hand. This material in a rough state is rarely ever seen, as most of it is processed into jewelry, as honestly it is economically more beneficial.
