taro ground (that means grains size around 0.5mm can easy see on eyes) bean green color GARDE A bangle, bit moist looking, very clean, don't see much flaws.
6000 yuan (usd around 1k) on year 2009
while ago i noticed one of my bangle has this black pencil line looking, did some reseach about it and just found out it ok to have it ...
that black pencil line can't wash it out though, but i think maybe re-polish it will help.
There the line on the bangle was scratched with some metal.
