A Fancy Coloured Diamond Single-stone RingThe marquise-cut fancy pink diamond, weighing 1.50 carats, ring size 4¾注脚Accompanied by a GIA report stating that the diamond is natural Fancy Pink colour. Report number 2195437442, dated 26 June 2018.1.50克拉天然粉紅色鑽石戒指戒指尺寸4¾,附GIA證書Pink DiamondsPink diamonds are extremely rare. Approximately 1 in 10,000 carats of mined diamonds are gem quality fancy coloured diamonds and of this small amount, 0.01% are fancy pink diamonds and the majority of these have a characteristic secondary hue, such as purplish pink, orangey pink or brown pink.The main source of pink diamonds for the past 25 years has been the Argyle Mine in Western Australia which accounts for around 90% of pink diamond production today.With no major diamond discoveries in the last two decades and with the Argyle Mine poised to shut down by 2021, good quality, fancy pink diamonds of all sizes and colour combinations are expected to remain highly sought-after and increasingly difficult to find.粉色鑽石粉色鑽石非常罕見,大約萬分之一克拉的開採鑽石能達到寶石級別的彩色鑽石，只有其中0.01％為彩粉色鑽石，而大部分夾雜了二級色調，如紫粉色，橙粉色或棕粉色。過去25年來，粉紅鑽石的主要來源是西澳州的阿蓋爾（Argyle）礦床，佔現今粉色鑽石產量的90％左右。其他來源包括印度，非洲（許多國家），巴西和婆羅洲。大多數開採的粉色鑽石都在1克拉以下，而來自阿蓋爾（Argyle）礦床的最大粉色鑽石約為4克拉。由於過去二十年沒有重大的鑽石發現，阿蓋爾（Argyle）礦將在2021年準備關閉，因此，在供求相對下,各種大小及顏色組合的高品質彩粉鑽石仍然將備受市場追捧。
