Where can I get Diamond-Cut aka Gem-cut crystal beads?

I have these earrings made from beads that look like loose diamonds and the hole is drilled on the side (not through the middle) so it hands like a pendant. Haven’t seen anything like that in bead stores. Maybe I have the wrong name?

Try stitchncraft.co.uk they do all sorts of fancy beads
