Diamonds are the most precious and enduring of all gemstones, with their very name taken from the ancient Greek word αδάμας (adámas) meaning 'unbreakable'. For centuries their exquisite beauty, inner fire and unique physical qualities have made them prized above all other gems.      鑽石是所有寶石中最珍貴和經久不衰的，其名稱取自古希臘詞 αδάμας (adámas)，意思是“牢不可破”。 幾個世紀以來，它們精緻的美麗、內在的火焰和獨特的物理品質使它們比所有其他寶石都更加珍貴。
