[Looking4] Huge twisted briolette bead

Hello all,

for a pendant I am looking for a faceted twisted briolette in smoky
quartz, which is about 40 mm high. It may be drilled into or through
the top, that does not matter for me. Does anyone have a good source
for something like that? That shape seems to be very common, but I
cannot find it in more than 24 mm.

I have uploaded an image, so you can see, what I am talking about:
