Onyx is a name used for both a banded variety of quartz and a banded variety of calcite, so don’t be confused by the term’s double use. Both types of onyx are used as decorative stone, but differ in their uses. Calcite onyx is much softer than quartz onyx and is more easily carved, so it is used for most ‘onyx’ carvings.These are used typically for binary mixtures of sandstone, limestone, or dolomite with gypsum, trona, salt, or sylvite. This plot is not particularly useful in fractured or vuggy formations nor for sandstone and limestone or limestone-dolomite mixtures. ... Calcite: CaCO 3: 2.71: 0 –1.Therefore, a cut calcite over 50 carats is extremely rare. Faceted stones cut from material from many localities might turn up, but the lack of scarcity value is not encouraging to potential calcite cutters.

This rock will strongly fizz when exposed to dilute hydrochloric acid ...Limestone. Rock Type: sedimentary Composition: mostly calcite Environment: There are several ways for limestone to form. Calcite dissolves easily in warm water but when the concentration reaches a certain threshold, the calcite comes out of solution and is deposited on the sea floor as a chemical precipitate.After precipitation of gypsum, the brine is both enriched in Mg relative to Ca and has a higher density. If the brine then enters the groundwater system and moves downward into buried limestones. This Mg-rich brine then reacts with the calcite in the limestone to produce dolomite. Mixing of Seawater and Meteoric Water.The primary difference between limestone and marble is that limestone is a sedimentary rock composed primarily of calcium carbonate fossils. In contrast, marble is a metamorphic rock composed primarily of calcium carbonate fossils. Shells, sand, and muck descend to the bottom of oceans and lakes, where they solidify into limestone over time.
