Sure can make a suggestion. Check Barb Smigel’s site
Barb is a certified gemologist and a cutter herself. She’s based in
Las Vegas, and has been doing custom cut gems on the internet for (I
believe) twelve whole years now, which not only makes her a real
pioneer, but also testifies to her continuing commercial uprightness
and reliability. She uses known cutters from across the US; all
stones are coded with the name of the cutter, their degree of
wearability, and their various enhancements or lack thereof.
Usual disclaimer: not only do I have no commercial connection, it’s
worse than that: I facet-cut myself, so that makes Barb something of
a downright competitor. But inasmuch as I am still struggling to
properly photograph my stones I’m not quite ready to come out of the
closet with a web presence just yet. So check Barb’s site. To me, it
is in the nature of a benchmark.
