I was thinking same for black tourmaline as well except I was looking into purchasing large examples around 200-300 grams range. Not much sells that size except all I know is from ebay. Usually natural state.

I already had purchased 180 gram polished palm sized black tourmaline and large palm howlite as well.

Any other more crystals that does same to suggest?

I already have buddhist fish mokuygo and hammered singing bowl, both 6" Is there's singing bowl that bit higher pitch than mine would do?

Cheers, stonecollector.
