Hey Benz.

Answer: Yes, yes & yes. A combination of all...
Sometimes those 'chatter' flaws open up due to grinding wheels running a little wobbly. (got to get them as true as you can!)
They often appear at edges such as you are finding.
Often just part of the stone quality, or lack of. Some of the most attractive stones can be the most difficult (or impossible!) to work.
Sometimes running tools too fast can be the cause, experimentation with speeds & familiarity with particular stone-types will teach how to best avoid (if at all possible...) There is no easy answer Im afraid.

It is possible that these will 'ping' out at some point. There is never a guarentee & I certainly point these out & discount heavily if/when anything like this occurs (& it occurs frequently!!)

*True 'cracks' are easier to read & trust, and often serve well aesthetically.

It is pretty rare for a piece to be absolutely perfect, so dont give yourself a hard time! This is also fairly limited to jade (or other translucent stones), being kind of crystalline & brittle... 'Normal' stones, such as Paipo is using tend to be a bit more trustworthy in this regards..? Or do they chip/break Paip'?...

PM me your address Benz & Ill send you a variety of slabs to have a go with. Youre doing wonderfully & Im sure youll be thrilled when you have finished a few & can admire the added bonus of glowing TRANSLUCENCY, dribble... Tama
