最近市面上頻繁的出現了許多染色的黑蛋白及火蛋白
經本所判斷極可能為衣索比亞產蛋白石
物件通常都具鮮豔的顏色以及明顯的遊彩
但拉曼光譜下顯示出染料的特徵峰
難逃台灣聯合鑑定中心三位鑑定師的法眼
據知目前有些流竄在市面上的染色蛋白石
還具有國際級鑑定所的開立的天然蛋白石證書
消費者不可不防吶

TULAB gemologists identified those opal as dyed Ethiopian opal, for characteristic raman spectra of dyes. According to our customer, those dyed opal are certified by some famous international gem lab, however dying treatment is not in the comment of report.
