Thanks Heimo. Romanian minerals have been a focus of my collection for over 30 years and this is the only calcite that I have ever seen from Herja with this habit. Glad you like it.

Thanks Tobi. That's what I thought when I saw it. I have several other aquas from that area of Pakistan, and a couple are quite a bit larger, but I just love the aesthetic arrangement of this one.

| Description: |
| Willard Perkins, who developed the "Perky box" often mounted specimens on a comb tooth stuck in the styrofoam box liner. This Perkins mount was purchased from him by Beth Gordon in 1982 and later became part of Wendy Melanson's thumbnail collection. I will usually remount most of the thumbnails that I acquire, but when I am fortunate to find an original Perkins mount I leave it as is. |
