I just looked at the latest Gem-o-rama flyer, and they have the rectangular Abalone beads (illustration shows they're drilled the long way) like I used on the Green Hill Necklace. They call them "Albalone Nugget Beads," which is a good description, since mine are triangular in shape. (Think of the play-doh fun factory with the triangle die. Cut the triangle bar into 15mm lengths, and that's what I have)
Price is decent, too. $13.50/strand.

BTW, if anyone does place an order from them, could they drop me a line? I want one of those blister pearls that they're advertising, but that's the only thing I want from this flyer and don't want to bother with an order for just one thing.
