決定珍珠價位的六大因素 The Six Determining Factors for Pearls Pricing

²影響珍珠價位的六大因素包括:

(a). 大小 ~（mm）測量尺寸以珠的腰圍(直徑)大小為準，愈大價位愈高。

(b). 形狀 ~ 分為六大類型: 圓形Round、近圓形(Near Round) oval、鈕扣型Button、水滴形Drop、變型(畸形)珠Baroque、有腰帶Circle。

(c). 顏色 ~ 南洋珠有白、香檳、銀、金色等，淡水珠大都是白色（但沒有金珠與黑珠），

大都沒有光澤及光滑表面，因此許多淡水珠都需做打磨刨光及染色加工處理。

(d). 光澤 ~（表面皮光）是決定價位最主要因素。

(e). 瑕疵度 ~ 瑕疵點分布面積越小，價位較高，當然沒有瑕疵的全美珠為最高價。

(f). 厚度~（mm）珍珠層的厚度是越厚越好，Akoyo 珍珠則為0.15mm~3.5mm，而大溪地當局嚴格限制珍珠層厚度達0.8mm以上才能出口，而南洋珍珠厚度則為2mm~2.5mm。

(a) Size – Measured in millimeters, the bigger a pearl’s diameter, the higher the price.
(b) Shape – Classified in 6 groups: Round, Oval, Button, Drop, Baroque and Circle.
(c) Colour – The overtone colour of South Sea pearls consists of white, champagne, silver
and golden etc. Fresh water pearls are mainly white colour (never in gold or black) and mainly lack luster and smooth surface. Therefore, most fresh water pearls go through treatment processes such polishing and colouring.
(d) Luster – This is the chief determining factor in pricing pearls.
(e) Flawlessness – The lesser the flaw, the higher the price. A flawless pearl command the highest price.
(f) Nacre thickness – Measured in millimeters, the thicker the nacre the better. Akoya pearls nacre thickness ranges from 0.15 to 3.5mm. Tahitian authority imposes strict regulations which only allow pearls with at least 0.8mm nacre thickness for exportation. South Sea pearls nacre thickness ranges from 2 and above.
