I’m glad to see that they are accepted to some degree. I enjoy
cutting lab created material much more than natural because it allows
me to be more creative without worrying about (a) prohibitive cost of
rough, (b) size of the stone I want to cut, © worrying about final
carat weight (trying to get the most for what I spent on the rough).
I like to cut unique designs. If a customer insists on natural, so be
it, but like the emerald conversation, it’s going to cost more money.
There are some great synthetics out there with optical properties
and color combinations that do not occur in nature. Also, some great
color change material in high RI. I’m cutting a custom oval/cushion
right now in a piece of burma blue synthetic material with an RI of
1.93. I expect it to be extremely lively and bright. I have to
replace a stone in an old silver casting (very old) but the
individual doesn’t want to spend a lot of money (I suspect the
original stone was fake). I need a very high RI because the angle on
the pavillion has to be very low since the setting is very shallow.
The lower the pavilion angle, the higher the RI has to be. I could
have gone the CZ route but I don’t like CZ very much.
