Advice needed on vintage jade bangle

[CleoHere]

Hi everyone, I am new to most vintage jewellery and am more of a clothes lover. I purchased this jade bangle with other vintage pieces. I was told this was Chinese jade/ jadeite but didn’t question it as I would a Bakelite piece. I’d love people’s opinion on: a) whether it is genuine; b) what sort of grade/ quality it is; and c) how much I should (if I do) seek it for? Any information or tips would be amazing.

It looks like glass, imho.

Yes, the colours and way they are distributed isnt how Jadeite or Nephrite is formed so I would say it is glass or a best grade C “Jade”.
The grading of Jadeite is on its treatment, A being entirely natural and just polished, B with more intrusive treatments and C basically bleached, dyed and glass filled within an inch of its life.
Obviously only proper testing can confirm or deny that but the cost of testing will be more than the bangle is worth.
There are dozens and dozens of similar bangles on eBay (photo) for less than $10.

I say glass. Those swirls are a dead giveaway.
