- Wow! THIS is a nice calcite specimen! The nice forms, hematite zoning, pyrite sprinkles and historic, classic location make it extra special. This location was mined for electronic-grade quartz crystals during the second world war and they also came across these excellent calcite clusters, as well. Looks fantastic!

- This is one ugly specimen! but it IS interesting! It consists ofa main portion of dark, smokey quartz which has crystals of a number of minerals attached to it but most interestingly, zircon, variety cyrtolite. There are quite a few well formed, tetragonal zircon crystals scattered about. This old mine has now been "reclaimed" and collecting opportunities there will be minimal in future. TS
