But, even if the current name stamp stones are much softer, there
are people out there who carve quartz. Plus there might be other
means such as chemical etching or sandblasting with a mask, right?
It is true that chemical etching and sandblasting are possibilities,
but I don't recommend either process. Aside from the hazards
involved both are fairly slow procedures. You can carve amethyst
with a flex shaft, diamond points, and dripping (maybe even running)
water. The secret is not to let the stone heat up from the friction.
The amount of water needed is based on the speed and pressure used.
You can use any cheap piece of quartz to learn with and directly
translate that new knowledge to the more expensive amethyst. A drill
press or carving arbor can also be used.
I don't know of anyone in your area currently who is doing this type
of carving. I specialize in carving seals and signets in gemstone
and will be more than happy to offer any further advice or
