Here we have a rarely seen and notably fine quality example of the Zinc-bearing variety of Dolomite (Zincian Dolomite), with a gentle silvery-blue color, and superb pearlescent luster. Hundreds of fine quality, slightly curved rhombic crystals measuring up to 5 mm, comprise semi-spherical aggregates, covering the underlying matrix.

Dolomite is a harder-than-average material and is not as fragile as marble. On the Mohs hardness scale, dolomite rates at 3.5 – 4, superior to marble’s Mohs rating. A higher hardness rating makes it a durable and strong countertop over time, capable of supporting various uses while being resistant to wear and tear.

Dolomite is composed of calcium and magnesium carbonate, and is quite similar to calcite. There are a few different varieties of dolomite. Pale brown, gray, or white dolomite with a pearly luster is called pearl spar. Brown dolomite, colored by iron, is called bitter spar. Dolomite crystals can also be colorless, yellow, or pink.Dolomite has a Mohs hardness of 3.5, which is slightly harder than calcite. Dolomite also etches more slowly than calcite, but it will still etch. Example: Super White a well known dolomitic marble that is frequently mislabeled as quartzite.

One other difference you may see is the smoothness of the crystal faces on your specimen.Reservoir characterization of the Mississippian Madison Formation, Wind River basin, WyomingCalcite is a carbonate mineral CaCO3 ( Fig. 1.13 ), and the most stable polymorph of calcium carbonate (calcite, aragonite, and vaterite). The color is milky white due to transparency with a yellow tint. The luster is vitreous with a white streak. The specific gravity of the mineral is 2.71 g/cm 3. The nodules can be small, around 5 cm in diameter, sometimes reaching more than ~30 cm in width, or bedded, as chert layers between the dolomite layers. The cherts show varying degrees of dolomitization and are mostly characterized by a coarse to semi-smooth feel and dull luster, often showing fractures and alterations.
