这块外部晶莹剔透、内部璀璨的华美宝石,既不是图像合成的产物,也不是人造宝石,而是一枚纯天然的蛋白石。当光线照在这颗蛋白石上时,会在其中发生折射,呈现出斑斓的色彩。这块宝石产自蛋白石之都——澳大利亚的库珀佩蒂镇。远古时代,这里生活着大群的蛇颈龙,它们死后沉入海底,数万年后变成了蛋白石。所以有很多人认为,蛋白石就是蛇颈龙的化石。
This external crystal clear, bright internal gorgeous gems, neither the product of image synthesis, nor is it a man-made gem, but a pure natural opal. When the light shines on this opal, there will be refraction in it, showing a gorgeous color. This gem is from the Opal Capital - the town of Cooper Petit in Australia. In ancient times, there lived a large group of plesiosaur, which sank into the sea after death and became opals after tens of thousands of years. So many people think that opal is the fossil of the plesiosaurus.
