What a beautiful collection of crystals, and also rock formations, crevices models, and even the architecture of the Museum looks like a twin topaz! Below is my new post of pictures taken there, in the heart of Downtown Dallas, the Ross Perot (former Presidential candidate in the USA). Name the crystals! I will have to make another visit to the area, as I just saw half of it, as it was already late when I made it. The specimens go from Schellited to tourmaline, beryl, wulfenite, native gold, gypsum, etc. Enjoy them, I took my iPhone 4S to work hard.
