Jade is a pretty hard substance (I believe it can stratch glass); however, it can break if it is hit in the right spot or dropped (that happened to a beloved ring of mine - I dropped it and it broke in half, so I had it glued back together, but was advised by my Asian friends not to wear it since it's protective value is now lost - hey, the Chinese take their jade very seriously
). Otherwise, I never had a problem with any of my other jade - rings, pendants, bangles. Def not high maintenance. Just put it on and forget about it. If you do purchase a bangle, make sure it fits rather snuggly so you don't bang it all over the place. My green baby is on the narrow side and light, so if I'm typing on my laptop (like I am now), I just push it up my arm a bit. Never scratched or scuffed my jade (again, it is pretty hard substance so don't baby it, but don't drop it either).
