yingyujade.com or jadebanglebracelets.com review: not good jade bangle like the shop owner claiming on the website

I bought a on-sale jade bangle for 188 $ plus 10 $ for shipping. At first I think it is really great. It color is apple green and icy white like description on the website. However, when I strike it with a coin, it sounds dull not high pitch. Its surface seems to have small scratches. A real jade a jadeite should not have scratches on its surface. I am really disappointed. I can not return it because on-jade jade is final sale. This is my first bangle. I just write a complaint here in case someone find it helpful before buying from the websites. If you buy from the shop, make sure buy jade with certificate
