Why Buy Certified Jade: Protecting Your Investment

Without laboratory testing, it is nearly impossible to distinguish between natural Type A jade, treated Types B/C/D, and imitation materials like serpentine or aventurine. Why Treatment Matters: Type B jade is chemically bleached and filled with polymer that can yellow over 5-10 years. Type C jade is dyed and can fade. Type D is assembled from smaller pieces. Trusted Certification Bodies: GIA (globally recognised), HKJSL (specialises in jade), NFTC, Gem-A, SGS. What to Look For: Certificate from a recognised laboratory, clear 'Type A' declaration, unique verifiable certificate number, detailed measurements. At Jade Heritage, every piece comes with certification from accredited laboratories. We also display the original purchase receipt for full provenance transparency. Remember: if a deal seems too good to be true, it probably is. Natural Type A jadeite of good quality commands significant prices.
