🔍Key Identification Characteristics

Visual and physical traits that help identify authentic jade jewelry

1 Cool to the touch initially but warms slowly in the hand — glass and plastic feel different
2 Smooth, waxy to vitreous luster on polished surfaces
3 Jadeite ranges from translucent imperial green to lavender, white, and yellow; nephrite is typically darker green, white, or black
4 High density — genuine jade feels heavier than it looks compared to glass imitations
5 Fibrous internal structure visible under strong backlighting in thin sections
6 Resists scratching — jade is 6-7 on the Mohs hardness scale, harder than steel

🔎Common Marks & Labels

Stamps, signatures, and labels to look for on jade jewelry

Gold or silver setting marks: 14K, 18K, 750, or 925 on the metal mounting
Chinese characters carved into the reverse or setting, sometimes indicating the workshop
Gemological laboratory certificates (GIA, HKJL) for high-value jadeite pieces
Seller tags from reputable jade dealers in Hong Kong, Taiwan, or Myanmar

💡Expert Tips

Tip 1

Hold the piece up to a strong light: natural jadeite shows a fibrous, interlocking crystal structure inside, while glass imitations appear uniform or bubbly. Dyed jade shows concentrated color in fracture lines

Tip 2

Tap two jade pieces together — genuine jade produces a clear, musical tone. Glass makes a dull click

Tip 3

Beware "treated" jade: Type B jade has been acid-bleached and polymer-filled to improve transparency, and Type C has been dyed. Only Type A (natural, untreated) jade holds its value
