Carved Cabochons Source?

I am looking for a source for cabochons that are carved with images
of flowers (petals, cross-hatching in center, etc.) in the following
materials: tourmaline, amethsyt, citrine, moonstone, aquamarine.
They have been traditionally carved in India in a wide range of
materials. It is these carved cabs from India that interest me. My
original supplier for these stones is no longer able to get them.
All help appreciated.
