除了鑽石外,其它寶石都可稱為有色寶石。有色寶石在價格方面沒有鑽石的穩定性,它的行情因地區、流行而變動。例如翡翠深受中國人的喜愛;蛋白石、碧璽、拓帕石等則為日本人所獨鐘。評定有色寶石本身的價格要素有重量大小、顏色色系、瑕疵、雜質、顏色濃淡、切工好壞。另外货源多寡、政治因素、景氣好壞等則是影響價格的外在因素。 In addition to diamonds, other gems can be called colored gemstones. Colored gemstones do not have the diamond’s stability in terms of price, and their prices vary by region and popularity. For example, jade is popular with the Chinese people; opal, tourmaline, topaz, etc. are the only favorite by the Japanese. The price of non-ferrous gemstone itself is determined by its weight, color, blemishes, impurities, color shades, and cut-offs. In addition the amount of supply, political factors, the economy is good and bad, etc. are the external factors that affect the price.
