This item is completely natural and has not undergone any chemical treatments. It has a gem-like color, and due to the high cost, we only purchased one piece. - Material: Jade - Origin: Myanmar - Length: Approximately 60cm - Bead Diameter: Approximately 8.1mm - With Certificate of Authenticity As this is a natural stone, there may be some minor, inconspicuous cracks. Please consider this before making a purchase. Thank you for viewing. --- I am selling these as a hobby and have set the price with a small profit margin, so I am unable to negotiate a significant price reduction. However, a small discount might be possible.
