I was able to locate the term scorolite in a paper on
geoenvironmental hazards in groundwater in India. It was cited as a
source of arsenic in the groundwater.
The paper gave a formula for scorolite which turned out to be that
of scorodite, an easy typographical error. Scorodite is a hydrous
ferric arsenate, and there is an article and picture in mindat:
It can come in a color similar to that of the beads I saw online,
but the hardness is only 3-1/2 to 4.
I don’t know where this bead material is coming from, but the online
descriptions in Etsy, eBay and similar sites seem to be taken from
the same source, and are equally vague. They refer only to beads,
and describe the color, claim a color change in different lighting,
and that’s about it. Are the beads made of scorodite or is it a
misrepresentation or a made up name? I really have no way of saying,
but I hope someone tests a bead and finds out for sure what it is.
