Calcite doubly terminated.
TB37: Calcite doubly terminated
Aerial, with the two tips unbroken, and very well placed on the matrix. It also has good contrast between the matrix's colorless Calcite and the orangish main crystal. Esthetics!
Elmwood Mine, Carthage, Central Tennessee Ba-F-Pb-Zn District, Smith County, Tennessee  USA
Specimen size: 7 × 6.5 × 5.5 cm = 2.76” × 2.56” × 2.17”

Price: [SOLD]
Calcite doubly terminated.
JH14E5: Calcite doubly terminated
This one appeals to me because it is unusual. The Calcite crystals, which are very well defined, doubly terminated, and clear, appear to be randomly spread across the dark matrix.
Minerva I Mine, Ozark-Mahoning group, Cave-in-Rock Sub-District, Hardin County, Illinois  USA (±1980)
Specimen size: 8.8 × 6 × 6.5 cm = 3.46” × 2.36” × 2.56”

Calcite epitactic Rhodochrosite, Sphalerite, Pyrite.
11TP46: Calcite epitactic Rhodochrosite, Sphalerite, Pyrite
Rich group of Calcite crystals in epitactic growth on Rhodochrosite. The rhodochrosite acted as a substrate which controlled the shapes and orientations of the younger Calcite crystals. The specimen is completed by crystals of Sphalerite which form the matrix, and tiny crystals of Pyrite sprinkled between the white Calcite crystals.

Calcite on Aragonite and Sulfur.
SE97AC7: Calcite on Aragonite and Sulfur
Aggregate of very flattened Aragonite crystals with their characteristic pseudohexagonal shape. The surfaces of their faces are coated by small Calcite crystals and they have deformed Sulfur crystals on the back.

Calcite on Baryte.
NC9F2: Calcite on Baryte
On a base of laminar Baryte there are two curious groups of Calcite crystals; they look like sprays and their gray color contrasts well with the white matrix.

Price: €80 / US$90 / ¥10230 / AUD$120
Calcite on Dolomite.
ET60E4: Calcite on Dolomite
I think the photo says more than I can explain. The white crystals are not what they look like: they are Calcite, so don’t be mistaken. The brown ones are what they look like: Dolomite.
Roata Mine, Cavnic, Maramures  Romania (2004)
Specimen size: 3.5 × 3.4 × 2.9 cm = 1.38” × 1.34” × 1.14”

Price: [SOLD]
Calcite on Prehnite.
JA76E7: Calcite on Prehnite
There is good contrast between the yellow Calcite and the green spherical Prehnite. The crystals of calcite are well positioned on the Prehnite matrix and the overall effect is delicate and soothing. A very fine specimen.

Price: [SOLD]
Calcite on Quartz.
RR46G0: Calcite on Quartz
Excellent representation of Calcite from Guanajuato. The specimen is especially esthetic due to the aerial position of flat rhombohedral crystals, with a lenticular habit, on a matrix of lightly violet Quartz.
Guanajuato, Guanajuato  Mexico (±1967)
Specimen size: 5.7 × 5.3 × 3.6 cm = 2.24” × 2.09” × 1.42”

Calcite replacing Mercenaria sp.
TA58H2: Calcite replacing Mercenaria sp
This kind of “boat” is a fossilized shell of Mercenaria sp, the interior of which is now occupied by honey-colored Calcite crystals filling most of the available inner space. The Calcite crystals “borrowed” calcium from Mercenarias for their growth.
Ruck's pit, Fort Drum, Okeechobee County, Florida  USA (2003)

Calcite with Aragonite.
TX97AH3: Calcite with Aragonite
You can opine, perhaps, that Calcite is a “modest” species, but it can also reach unexpected heights of elegance as in the case of this complete crystal that is clear, colorless, very rich in faces and has additional elongated Calcite and Aragonite crystals with curious parallel growths. Due to its special transparency, the Calcite crystal has a high birrefringence that allows one to see “double” images through it.
Verkhnii Mine, Dalnegorsk, Dalnegorsk Urban District, Primorsky Krai  Russia
Specimen size: 4.4 × 3.7 × 2.9 cm = 1.73” × 1.46” × 1.14”

Calcite with Baryte, Dolomite and Fluorite .
SM480NF: Calcite with Baryte, Dolomite and Fluorite
Complex crystals of Calcite, translucent, bright, yellow in color and on matrix, with Baryte, Dolomite and Fluorite. The yellow color of the Baryte and the general appearance of the piece is different from what is usual at this mine and corresponds to a small vug from which few pieces emerged.
Moscona Mine, El Llano, Solís, Corvera de Asturias, Comarca Avilés, Asturias, Principality of Asturias  Spain (2018)
Specimen size: 14.6 × 10.6 × 7.1 cm cm = 5.75” × 4.17” × 2.80”
