rubies是名詞"ruby"的複數形式,指代一種稀有珍貴的紅色寶石。作為剛玉礦物(化學成分為Al₂O₃)的變種,其紅色來源于鉻元素置換晶體結構中的鋁原子,顔色範圍從粉紅到深血紅不等。這種寶石在莫氏硬度表中位列9級,僅次于鑽石,因此兼具美觀性和耐久性。
在曆史文化中,《聖經·箴言》31章10節用"其價值遠勝過紅寶石"形容賢德女性的珍貴。中世紀歐洲王室将紅寶石鑲嵌于皇冠,象征權力與神聖性,如波希米亞聖瓦茨拉夫王冠上的250克拉紅寶石。
現代寶石學依據4C标準(顔色、淨度、切工、克拉)評估紅寶石價值,其中産自緬甸抹谷的"鴿血紅"品種因飽和度高、熒光效應強被視為頂級品質,2023年蘇富比拍賣會上曾以3480萬美元成交一枚55.22克拉緬甸紅寶石。
以下是關于單詞“rubies”的詳細解釋:
"The crown was decorated with rubies and pearls."(王冠鑲嵌着紅寶石和珍珠)
"Today rubies are also created synthetically in the lab."(現代紅寶石可通過實驗室人工合成)
