    Red Beryl, and Topaz, found at Topaz Mountain, Utah, United States [OC]

    The Red Beryl, or Bixbite, and this Topaz cluster were found on different days, different visits, to the same location. I placed them together for this photo. I have found lots of Topaz at Topaz Mountain, however, this is the only Red Beryl I own.

    The surface of this stone looks like a miniature map of nature. The twists and turns in shades of brown and orange almost look like small mountain ranges or hills. The dark gray areas remind of deep valleys or mysterious caves. And the empty spaces in the middle look like dried up lakes / geysers!

    Piece of the Gibeon Meteorite [OC]

    I had the opportunity to photograph a small piece of the Gibeon Meteorite, a piece that has been sculpted. The weight of the iron and nickel, Widmanstätten pattern in it; such a fantastic piece, and I love it!!

    Tourmalinated Quartz [OC]

    37 years ago I got chunk of Quartz. I carried this with me everywhere because I thought it was amazing, and as a six-year-old, I dropped it, a lot (you can see the chips and points of impact 🤦‍♂️). Anyway, my whole life I thought is was Smokey Quartz. A year ago a friend corrected me by pointing a high-powered flashlight at it. Turns out this is Tourmalinated Quartz, and I have been wrong my whole life 😂
