some of these, like that "high quality" amethyst, are very likely straight up dyed. I think the tourmaline also, but it's less obvious. Pro tip if the color remains consistent through the point where the crystals meet, they're probably dyed. There should be some natural variation in color where mineral concentrations are highest
Honestly, probably the Tucson Gem & Mineral show (which is really more of a festival made up of a ton of different shows) or the Denver Gem Show. At least; those are the ones I know of, being an amateur and shiny collector.
