Had some exceptional Canadian jade (nephrite) years ago, also some presumably-some-sort-of-serpentine beads that they referred to as "Flower Jade."
"Flower," as I believe Russ once explained, is a Chinese stone vendor catch-all term for "something-that-resembles-X-stone-but-isn't-it".

If anyone cares, let me know and I'll rummage through my storage boxes and take some pics.
