[Source] Fine carved cabachons

Hi All, I was wondering if anyone here had any clues as to where you
can find fine carved cabachons. Saw a beautiful carved garnet that
reflected the light beautifully. Also saw carved citrine, amethyst &
carnelian. Some of the carvings were a floral motif & some more
abstract. Then there were some small gemstones carved into actual
flower shapes that could be set into a ring. They were very very well
done. I have a feeling these cabs are probably done over in Europe.
Anyone have any ideas where to look?
