Tumbling will not take off a tiny thickness all across the piece. Instead the grit will selectively attack certain parts of the stone. Rotary tumblers will change the shape more than a vibratory tumbler
Ideally, depending on the stone, the sand pits are small and shallow. If you are just using a standard lapidary grinder setup you just grind through the pit. And leave a smooth cabochon surface.

Since they have crumbly textures, they may also undergo polymer treatment for stabilization. Hydrophane opals can be dyed or smoked to alter their body colors Clean, smooth gems can be used to great effect in jewelry or in craft projects. Or, they can simply be decorations or additions to an existing rock collection. But when a gem is extracted from the ground, it is rough and dull.
