i found a salt called cyprus flake salt that is defined as:
"A light crystal salt reminiscent of snowflakes. Seawaters are evaporated by the sun and wind producing salt brine that is slowly heated to the point where delicate
pyramids shaped crystals of salt appear. The finished product is light, flaky sea salt."
(from http://www.thenibble.com/reviews/main/salts/salt-glossary.asp)
if you'd like to see a picture and see them for yourself, here is a link to a good site to buy some from that is made from the mediteranean:

they have a perfect pyramid shape, very beautiful, most likely capable of containing and generating great energy (but then you grind them down to a powder.....almost a waste it seems
lol).
