I have collect some beautiful nephrite jade and chrysoprase rough material and
learning to cab it.
Would you tell me :
How to polish nephrite and chrysoprase?
What polishing material to be use will better?
I’ve polished chrysoprase few times. The result was absolutely amazing.
First, I have to say that I’ve cut it with a facetting machine, using a 400
and 600 grit lap. I did it like an oval’s crown and, always using the
facetting machine, I gently rounded the girdle’s and facet’s edges by hand,
with a 600 and 1200 grit lap, to obtain a perfect oval shape and a perfect
dome. Secondly, I polished the cab by hand with a Spectra Lap. I obtained
a superb luster, like if water was flowing over it.
