Scolecite is a mineral member of the zeolite group that gets its name from the Greek word for "worm" because of the way that the borax bead that contains the mineral sometimes curls when heated by a blowpipe. Scolecite possesses pyro- and piezoelectric properties. Enormous scolecite crystals have been found in Rio Grande do Sul, Brazil. For gemstone use, faceted scolecite is rare.
I love GemSelect, personally. I browse their site almost daily to see all the new stones available. Their selection is pretty amazing. The quality isn't always the highest and the cut of the stones isn't always perfect. But for the price, and if you look hard enough, you can find a real gem, so to speak.
