A stone is a stone. If it is polished well, it is still a stone.
There isn't any special reason for making the customer pay more
for it since it is just a stone.
ah larry -
after reading your post it occurred to me that either you have been
cutting the wrong stones or you need to get away from the workshop
to brush off the burnout ashes. i had beginner's guilt about
fabricating/forging $10.00 worth of sterling, using about $1.00 in
melee stones with a $1.00 to $5.00 stone i cut and polished, and
pricing the finished piece at $400.00 to $500.00 - what got me over
the guilt was that they sold! and repeat customers who continue to
pay my price - one reason is customers can tell that i love what i
do and they come back again and again to see - and buy - the latest
so, if you think 'a stone is a stone,' etc. consider hiring a rep
between you and customers, who can usually feel "if he's not happy
with what he does why should i spend money for it?"
so when is a stone not "just a stone"? when it brings pleasure to
someone who wears it.
good luck -
