Sure, this is "just" a quartz crystal, but it is clear from looking at it why Marty Zinn had it in his collection. What makes it special is the overall impact: that the back of the crystal is covered with orange dolomite crystals, which wrap around the front stopping at exactly the right point to create a "frame" for the quartz crystal! The quartz itself is gemmy and perfectly euhedral, and there are some interesting sulfide inclusions at the bottom. What a striking quartz specimen, and from a great old locality!
