Fake vs Real Jade: How to Tell, Tests & Treatment Grades

Real jade refers to natural jadeite or nephrite that has not been artificially enhanced. Fake jade includes glass imitations, dyed quartzite or serpentine marketed as jade, and polymer-filled jadeite (Type B/C). The gemological distinction uses a three-grade system: Type A (natural), Type B (bleached/polymer-filled), Type C (dyed).

Jade treatment grade classification

1. Type A jade — Natural, untreated jadeite or nephrite; only wax surface treatment permitted; highest value
2. Type B jade — Bleached and polymer-impregnated; removes impurities but weakens stone structure over time
3. Type C jade — Dyed to enhance or alter color; dye fades with UV exposure and time
4. Type B+C jade — Both bleached and dyed; lowest grade of genuine jadeite
5. Jade imitations — Glass, serpentine, quartzite, aventurine marketed as jade; not jade mineralogically

At-home identification tests

Comparison

Compared to at-home tests, gemological certification (GIA, GRS, or equivalent) is the only definitive method for distinguishing Type A from Type B/C jade. Spectroscopic analysis detects polymer presence in Type B stones and artificial dye in Type C stones — neither detectable reliably by visual inspection alone. For purchases above $300 USD, certification is recommended.

Buying criteria summary

1. Request Type A certification — GIA or equivalent lab report before purchase above $300
2. Apply temperature and weight tests — basic filters to eliminate glass imitations
3. Examine color distribution — natural jade color is uneven; dyed jade is artificially uniform
4. Verify seller transparency — reputable sellers disclose treatment grade proactively
5. Avoid below-market pricing — genuine Type A in solid gold below $150 USD is not viable
