Biggsville 01:  Calcite on limestone:  8 x 6 x 2 cm (3.2 x 2.4 x 0.8 inches) - $15.00 sold

Biggsville 18:  Calcite on limestone:  9 x 6 x 3 cm (3.5 x 2.4 x 1.2 inches) - $10.00 sold

Numerous calcite crystals ranging in size from just a few millimeters up to the main crystal being 3 cm (1.2 inches) across are scattered heavily on a limestone matrix base.  There is a small nick on the main crystal as the lower left photo shows and a few other crystals have minor rubs but very few of these are truly clean.  A fine small cabinet specimen from this quarry.  $15.00

Somewhat unusual calcite for the location, likely from the very upper levels of the quarry.  Small tannish colored calcites coat a limestone base.  There is virtually no damage outside of very minor contacting to a few crystals along the edge of the specimen.  $10.00

Biggsville 19:  Marcasite on limestone:  4 x 3.5 cm (1.6 x 1.4 inches) - $4.00 sold

Biggsville 20:  Sphalerite in limestone vug:  4.5 x 4 x 4.5 cm (1.8 x 1.6 x 1.8 inches) - $20.00 sold

A small piece of limestone is host to several small marcasite crystals.  Only typical contact rubs/damage.  $4.00

A single 2.5 x 1.5 cm sphalerite crystal is positioned into an open limestone vug/pocket.  There is only a slight area of contact on the back of the sphalerite and it appears there is a clean cleave at the top back of the crystal.  Recently released from a mineral collection in Illinois - classic example of western Illinois material.  $20.00

Biggsville 21:  Quartz on Calcite/limestone - 8.5 x 7 x 1.5 cm (3.35 x 2.8 x 0.6 inches) - $10.00 sold

Biggsville 22:  Calcite, Marcasite on limestone: 10.5 x 7.5 x 3 cm (4.1 x 3 x 1.2 inches) - $12.00

Quartz is not often seen in good crystallized form in this quarry.  It is much more abundant in the O'Neal (Plymouth) Quarry to the south.  Finely crystallized quartz is positioned on a limestone/calcite matrix mix.  Collected in 2004 and only minor edge contacting on the back of the quartz.  $10.00

A chunky limestone plate is host to several calcite crystals (mainly at or under 1 cm across) along with marcasite crystals in and on calcite crystals.  No damage other than a few small rubs to calcite crystals along the edge of the specimen.  $12.00

Biggsville 14:  Sphalerite with Pyrite:  5 x 3.5 x 1.5 cm (2 x 1.4 x 0.6 inches) - $8.00

Biggsville 08:  Sphalerite with associated limestone matrix: 3.7 x 2.8 x 2 cm (1.55 x 1.1 x 0.8 inches) - $6.00  

Somewhat crude sphalerite crystal with numerous small crystal faces on the right edge with larger faces on the left and back side.  Some golden pyrite is also in association.  The photographs illustrate too much light coming back - sphalerite is much darker (nearly black) than shown here.  $8.00

Reference specimen of sphalerite with associated limestone.  There are a few crystal edges that are contacted and/or poorly formed and the association with limestone detracts from the overall presentation of the crystal.  Still, a good reference sphalerite from this western Illinois quarry.  $6.00

Biggsville 15:  Calcite with Millerite inclusions on limestone:  6 x 3 x 2 cm (2.4 x 1.2 x 0.8 inches) - $10.00

Calcite crystals up to 1 cm (0.4 inches) across reside on the top of a limestone matrix base.  Some of these calcites contain very small growths of millerite at their bases closest to the limestone matrix, giving a somewhat cloudy appearance to some crystals.  Only minor nicking to a few crystals on the edge of the specimen.  $10.00
