Red Flags Guide
Knowing what to watch for is your first line of defence against jade fraud. This guide covers the most common warning signs, from missing certificates to misleading trade names and online scams.
No Laboratory Certificate
highSeller claims jade is 'Type A' or 'natural' but cannot provide a certificate from a recognised gemological laboratory.
Warning Signs
- Verbal assurance only — 'trust me, it's natural'
- Certificate from unknown or unverifiable laboratory
- Seller discourages independent testing
- Claims that 'real experts don't need certificates'
What To Do
Never purchase high-value jade without a verifiable lab certificate. Request testing at GIA, HKJSL, SSEF, or NGI. If the seller refuses, walk away.

Price Too Good to Be True
highThe claimed quality (vivid colour, high translucency, fine texture) does not match the asking price. Fine natural jadeite commands significant prices — deep discounts are a red flag.
Warning Signs
- Imperial Green 'Type A' offered at a fraction of market value
- Seller claims 'direct from the mine' to explain low price
- 'Closing down sale' or 'must sell urgently' pressure tactics
- Online listings with stock photos and impossibly low prices
What To Do
Research current market prices for the claimed quality level. If the price seems impossibly low, it almost certainly is. Treatment or misidentification is the likely explanation.

'Brown Staining Means Untreated' Myth
highA common misconception that brown staining on jade proves it is untreated (natural iron-oxide staining). GIA explicitly warns this assumption is dangerous.
Warning Signs
- Seller points to brown areas as 'proof' the jade is natural
- Claims that treated jade never has brown staining
- Uses staining as justification to skip lab testing
What To Do
Brown staining cannot be assumed to mean 'untreated.' GIA documented that treated stones can be re-stained and then impregnated, making them appear naturally aged. Only FTIR can confirm treatment status.

Suspiciously Perfect Colour Distribution
mediumUnusually uniform, vivid colour throughout the piece — especially when combined with high transparency. Natural jade typically shows some colour variation.
Warning Signs
- Colour appears perfectly even with no natural zoning or variation
- Intense green in an unusually large area without any paler zones
- Colour visible concentrated along fractures under magnification (dye indicator)
- Vivid colour combined with suspiciously high transparency
What To Do
Examine carefully under magnification for dye concentrations. Request visible spectroscopy to check for dye vs natural chromium absorption. SSEF has documented cases where vivid colour with no chromium signature confirmed dyeing.

Misleading Trade Names
mediumMaterials sold under names that imply they are jade but are actually different minerals. GIA documents many misleading labels in the jade trade.
Warning Signs
- 'Australian jade' (often chrysoprase — a form of chalcedony)
- 'Indian jade' (often aventurine quartz)
- 'New jade' or 'Xiuyan jade' (often serpentine)
- 'Malaysian jade' or 'Transvaal jade' (often dyed quartzite or grossular garnet)
- 'Korean jade' (often serpentine or bowenite)
- Any qualifying word before 'jade' that refers to a location not known for true jade
What To Do
Treat 'name' as marketing and 'identity' as measured mineralogy. Demand species identification (jadeite, nephrite, omphacite) confirmed by lab testing, not just a trade name. If the seller cannot provide mineralogical identity, assume it is not true jade.

Coated Jade
mediumA surface coating applied to improve colour or transparency. GIA documented that coatings can significantly alter apparent quality while concealing the true nature of the stone underneath.
Warning Signs
- Surface lustre seems different from interior appearance
- Scratches reveal different colour underneath
- Item feels warmer than expected (coating thermal properties)
- Surface RI readings differ from what's expected for jade
- Fluorescence patterns differ between surface and interior under UV
What To Do
Careful magnification examination of edges, facet junctions, and any areas of wear. Lab testing (FTIR/Raman) can identify coating composition. Surface hardness testing on an inconspicuous area may reveal soft coating.

Fake or Manipulated Certificates
highCounterfeit laboratory certificates designed to make treated or simulant material appear to be certified natural jade.
Warning Signs
- Certificate number cannot be verified on the issuing lab's website
- Lab name is similar to but not exactly a recognised lab
- Certificate layout or logo quality looks poor or inconsistent
- Certificate details don't match the item (weight, dimensions, description differ)
- QR code on certificate leads to unrelated or non-functional website
What To Do
Always verify certificate numbers through the issuing laboratory's official website. Compare the certificate format against known genuine certificates from that lab. If anything seems off, have the item independently tested.

Online Marketplace Jade Scams
highE-commerce platforms and social media sellers offering 'jade' with limited or no quality verification, using stock photos and exaggerated descriptions.
Warning Signs
- Stock photos that appear on multiple different listings
- No lab certificate provided or offered
- Descriptions using vague terms like 'real jade' without specifying jadeite or nephrite
- Seller has limited history, no reviews, or recently created account
- No return policy or 'all sales final' for high-value items
- Claiming 'direct from Myanmar mines' without documentation
What To Do
Only purchase from sellers who provide verifiable lab certificates, clear return policies, and detailed item-specific photographs. Use buyer protection services offered by platforms. Have any significant purchase independently verified upon receipt.
