When sourcing Jade Buddha statues, the primary concern is distinguishing between Natural Jade (Type A), treated jade, and imitations like serpentine or glass. Buyers should request CNAS or CMA certified laboratory reports to verify the stone's authenticity. Key quality indicators include translucency (water head), color uniformity, and the absence of structural cracks or black spots. For high-end procurement, prioritize Nephrite (Hetian Jade) for its oily luster or Jadeite for its glass-like brilliance.
