One fine amethystine
double flower comes from India.
Spruce Ridge quartz is commonly sceptered, and in some cases is amethystine
or Japan-law twinned.
The quartz scepters from Denny Mountain are among the world's finest, and the beautiful "Raspberry quartz" scepters (colored by sparkling red inclusions), some of them amethystine
as well, are unique.
Traffic had been likewise brisk in the new specimens of amethystine
Japan-law twinned quartz out of the Tonglushan mine, Daye district, Hubei, which Collector's Edge had procured.
The amethystine color ranges from faint violet to a deep purple, and the contrast of gemmy amethyst caps on opaque, porcelain-white stems is particularly aesthetic.
Multiple generations of quartz (fine-grained, doubly terminated crystals, to large, transparent or milky crystals, to late amethystine scepters) and calcite (rhombohedrons, scalenohedrons, platy and hexagonal prisms) are common in most cavities.

gwindels are almost unknown)
The last (at last) among the Brazilian what's-news is a recent discovery of Japan law-twinned quartz at Santa Maria do Jetiba, Espirito Santo state--in fact, these loose crystals are not only Japan law-twinned, but manage to be sceptered and amethystine

gwindels are almost unknown).
Several types of quartz exist in the miarolitic cavities, including transparent crystals, smoky quartz, milky quartz and amethystine
quartz, some with inclusions.
The specimens that impressed me most were a 15-cm group of smoky quartz crystals capped by a small "scepter" of amethystine
quartz from Les Droites (the north face of the Mont Blanc massif), Haute Savoie, in the Eric Asselborn collection, and, from the same collection, an exquisite pink fluorite crystal group on smoky quartz.
