I bought some triangular amethsyt cabs from Rio Grande recently… nice
color, although the sides were bowed (curved), as opposed to straight.
Since I was making my own bezels, it wasn’t a big problem, but it did alter
the look of my design somewhat.
Has anyone else noticed what is now selling as “Grade A” amethyst would
have been “Grade C” a few years ago? Color zoning, veils of bubbles,
washed out color? I’ve noticed this from more than one vendor. Inquiring
minds want to know…
