CAL-1 Calcite and
Mimetite - Mapimi, Durango, Mexico; 2.75 x 2 inches (7 x 5 cm) Very sharp glassy calcite rhombs partially cover golden brown
botryoidal mimetite. This one is perfect and very aesthetic. |
 |
CAL-2 Calcite -
Bisbee, Arizona ; 5 x 3 cm, $40, I have three pieces of a very interesting lustrous
complex twinned crystals from Bisbee. The first has glassy tabular crystals to 1.8
cm on matrix. These almost look like cerussite crystals. These are neat and
this one is the best of the bunch. |
 |
CAL-3 Calcite - Bisbee,
Arizona ; 3.5 x 3 cm, $35, This one is a single complex twinned crystal. Sure
to be desired by Arizona collectors. |
  |
CAL-4 Calcite -
Sweetwater Mine, Reynolds Co., MO; $50 Large
(16 cm) group of parallel growth crystals. Good color and crystallization. |
 |
CAL-5 Calcite – Ton
Mawr Quarry, Pentyrch, near Cardiff, South Glamorgan, Wales; 5.5 x 5 cm, $20, This
piece consists primarily of one large stacked rhombohedral crystal 4.5 cm long with a nice
termination. This ones attractive and in good condition and would make a nice addition to
a calcite collection. |

CAL-6 Calcite – Taffs
Well Quarry, Pentyrch, near Cardiff, South Glamorgan, Wales; 4.5 x 4 cm, $8, Nice
lustrous glassy small (4 mm) rhombs cover the surface. This piece is in excellent
condition and would make a good locality specimen for a calcite collection. |

CAL-7 Calcite –
Southwest Mine, Bisbee, AZ; 6.5 x 4 cm, $25, Superb sample of cavern-like
calcite growth from one of America’s premier mineral locations. The calcite grades
from a crystal growth to a curving twisted round growth at the end. The piece is perfect
and would make a great addition to any collection especially calcite or a Western US
suite. A few blue-green specs from copper inclusions. This piece came from the auction of
long time Tri-State District mineral dealer Brown’s Minerals in Joplin, MO and was
likely collected 30+ years ago as none of these have been collected for years. |

CAL-8 Calcite - Mid-Continent
Mine, Treece, Kansas; $40 Large golden
tabular twinned crystal 3 1/4 x 5 inches (9 x 13 cm) in size from the old Tri-State
District. The unusual tabular shape is the result of twinning and is a nice example from
these mines that have been closed and flooded for nearly 30 years. You can't dig these
anymore. I want to note that like most of the crystals from these mines this has been
quickly dipped in acid to brighten the luster. The old miners who collected these nearly
all did this and I would bet most pieces offered on the web have also been dipped (or
"Chinked" as we say around here named after one of the most colorful of the
miners, Chink Enders who immidiately did this to every specimen he brought out of the
mines) weather the seller tells you or not. Don't let it alarm you. It is almost a
charachteristic of a piece from this world famous mining district |

– Taffs Well Quarry, Pentyrch, near Cardiff, South Glamorgan, Wales; 5 x 4 cm,

a great locality specimen for a calcite or barite collection . Sawn on base for
perfect display. |
