I'm a jade lover and I bought this traditional round jade bangle along with 15 others as I love jade bangles at a jadeite market in Guandong. I bought it for $100 each. I'm selling it for $52. This one is a decent quality. It’s a solid, heavy, and sturdy piece—typical of high-quality jade. While I didn’t get a certificate due to time constraints (would’ve cost $4 and taken 2 days), the jewelry store guaranteed it’s untreated Grade A jadeite. I also did my own UV and flashlight tests for reassurance. If you love it, buy it! No certificate.
