點樣識別假翡翠？5個紅旗警號
- 價格過低：高質翡翠唔可能平到離譜
- 顏色過均勻：天然翡翠顏色分佈唔均勻
- 表面有氣泡：注膠翡翠在放大鏡下可見氣泡
- 手感過輕：真翡翠密度高，手感沉實
- 冇鑑定書：正規翡翠應有 GIA 或 NGTC 證書
翡翠鑑定書點睇？
正規翡翠鑑定書由 GIA（美國寶石學院）或 NGTC（國家珠寶玉石質量監督檢驗中心）出具。鑑定書上應清楚列明：天然翡翠（Natural Jadeite）、未經處理（No indications of treatment）。
What Is Type A Jadeite? The Three Grades Explained
Type A jadeite is natural, untreated jade — no bleaching, no polymer filling, no artificial dye. It is the only grade that retains its natural structure and long-term value. Type B jadeite has been acid-bleached to remove impurities, then filled with polymer resin. Type C jadeite has been artificially dyed to enhance or fake colour.
What Makes Good Type A Jadeite? The Five Value Factors
- Texture (種/Zhǒng): Translucency of the crystal structure — Glass > Ice > Icy-Glutinous > Glutinous > Bean
- Colour (色/Sè): Imperial green commands the highest premium; lavender, yellow, and white are also valued
- Clarity (淨/Jìng): Fewer inclusions, cracks, and blemishes = higher value
- Cut (工/Gōng): Proportion, symmetry, and surface finish
- Size (大小): Larger pieces of equivalent quality are exponentially more valuable

Type A jadeite is natural, untreated jade — no bleaching, no polymer filling, no artificial dye. It is the only grade that retains its natural structure and long-term value. Type B jadeite has been acid-bleached to remove impurities, then filled with polymer resin. Type C jadeite has been artificially dyed to enhance or fake colour.
5 Red Flags That Suggest Fake Jade
- Price too low: High-quality jadeite cannot be priced absurdly cheap
- Too-uniform colour: Natural jadeite has uneven colour distribution
- Bubbles under magnification: Polymer-filled jade shows bubbles under 10x loupe
- Too light: Real jadeite has high density and feels substantial in the hand
- No certificate: Legitimate jadeite should come with a GIA or NGTC certificate
How to Read a Jade Certificate
A legitimate jade certificate is issued by GIA (Gemological Institute of America) or NGTC (National Gemstone Testing Centre, China). The certificate must state: Natural Jadeite and No indications of treatment. Any certificate that only says 'jade' without specifying 'jadeite' or 'natural' should be questioned.
