Lepidolite can occur both in plate crystals and in massive form (right to left, respectively). The beads that you see are fashioned out of the massive form, and are most commonly deep lilac to dingy mauve in color with inclusions ranging from black to green to whitish to pink (in the case of rubellite (tourmaline)). Fire Mountain Gems has a very respectable selection, mostly C to D grade (with a lot of inclusions). A-grade (bright lilac, rubellite inclusions) is typically hard to find, and from what I have seen mostly comes from California and Maine.

These beads (interspersed with Sterling silver) are the pride of my collection. The rough came from the Pala district of California (I suspect perhaps the Stewart Mine, though I'm not entirely sure) and has a number of rubellite inclusions, which greatly add to the character of the beads. I found these by a stroke of pure luck at a rock shop in Vernal, Utah.
Yet another reason to scout out rock shops when looking for that elusive semi-precious stone. :)
For those of you who either live in or plan on visiting southern California, definitely plan on taking a trip to Gems of Pala. The mine is known for its world-class tourmaline, but along with that tourmaline comes that near-perfect lepidolite. It's a fun excursion for any rockhound, and you could very well come out with a gem-quality tourmaline and a mass of lepidolite perfect for carving or stashing in your personal rock collection.
So is lepidolite worth introducing into your beading repertoire? If you enjoy a stone with diverse character and interesting color, then most certainly yes.
