|
|
Here is a piece...not great, but special to me as I was able to collect it from inside the mine.
| Mineral: | Fluorite on Quartz with Pyrite |
| Locality: | | Sweet Home Mine, Mount Bross, Alma District, Park County, Colorado, USA | |
|
| Dimensions: | 157 x 112 x 56 mm |
| Description: |
| Light purple cubes of lustrous, transparent Fluorite to 12 mm cover a matrix of white needles of Quartz to 17 mm long with brassy Pyrites to 17 mm and less crystallized black sulfides. One portion of the specimen is in excellent condition, and it should be trimmed, but as is it is more geologically interesting. The back side is fully covered with fine needle Quartz and accented with black sulfides and brassy Pyrites. I self collected this on September 9, 2001 in the main haulage tunnel. |

...
| Mineral: | Laumontite with Calcite |
| Locality: | | Pine Creek Mine, Scheelite, Bishop District (Tungsten Hills District), Inyo County, California, USA | |
|
| Dimensions: | 112 x 102 x 77 mm |
| Description: |
| Slender, well-formed, twinned, prismatic Laumontite crystals to 70 mm long form a slightly diverging cluster. The terminations are classic fish-tail twins. Yellow Calcite crystals accent the Laumontite crystals. These specimens have been well preserved and looks like they may survive in spite of the mineral being so unstable. This is an excellent specimen from this long ago closed tungsten mine. |

|
|
A pair of well-formed, lustrous, opaque to translucent, brownish-yellow Diamond cubes with interpenetrant growth. The largest cube measures 9 x 8 x 8 mm. The faces are multicrystalline, giving the appearance of fine pitting. Sometimes referred to as Congo Cubes, these cubes are surprisingly sharp for this locality, and the twinning makes for a striking specimen. Purchased in 1995, this specimen has been tucked away for many years in my collection. Weight 13.6 carats.

Looking at the diamond, I would have never guessed that one correctly! That is a very neat oddity...
The wulfenites are also very attractive.

Hi Bob. I am also intrigued by the diamond specimen. Do you know what that pinkish colour on it is? Regards.

| It is "clay" of some sort. After the photos were taken, I was able to remove some of it with air abrasion.

This is reportedly one of the largest (if not the largest) Morganites found in California. It was found in 2005 by Dana and Ken Gochenour, and bought the same year by Al Ordway. Al kept it in his collection until his death in 2007. I acquired it in 2016.

Beryl is 113 x 105 x 93 mm
