“莹彩粉红”钻戒，成交价1180万美元，约合7670万元

A fancy vivid pink cushion-shaped diamond weighing 5.00 carats, mounted by Graff Diamonds. The rare pink diamond was mined in South Africa. According to Christie's website, unlike many other colored diamonds, the color in pink diamonds comes from the diamond's exposure to heat and pressure during transportation into the earth's crust.
莹彩粉红是一枚重达5克拉的枕形鲜彩粉钻石，并且镶嵌在著名珠宝品牌Graff设计的戒指之上。这颗罕见的粉钻是在南非开采得来的。根据佳士得拍卖行网页的资料称，与其他的彩钻不同，粉钻的颜色据说来源于地壳运动时钻石暴露在巨大的热量和压力之下而形成的。
