Rare Vintage Indo-Chinese Silver And Jadeite Jade Cuff Bangle - (69.5g)

Here we have a rare vintage silver and jadeite jade disc cuff bangle in good condition, however there is a small piece of silver missing around the the disc and there is a hairline crack on the jade disc but it is holding well and not falling out,. I have searched the internet but cannot find one the same nor similar so I think it maybe a one-off. It's beautifully decorated with flowers and the disc has a Chinese mark and it is stamped Indo-China at the end of the cuff. The bangle is heavy weighing 69.5g. It measures approx 38mm at it's widest point, the inner diameter is approx 63mm x 55mm and it's adjustable. Please do look at all the pictures as it is part of the description. Thanks for looking
