Blue Calcite: The Only Guide You Need
Blue calcite is quite soft when compared to other stones. It will instantly react when in touch with mild acids. For example, a bit of vinegar on a piece of blue calcite will make it fizz. The stone will dissolve. This is the main reason wherefore it is often acid dipped when used in jewelry.

Calcite
Calcite replacement is a common phenomenon in deep volcanic rock and volcaniclastic rock. Calcite may replace phenocrysts in lava and crystal fragments in volcaniclastic rock, and they also replace all types of debris and matrix. Extensive replacement may make the former rock texture unidentifiable or form replaced carbonate rocks.

Calcite Dissolution Kinetics | Aquatic Geochemistry
We compare the canonical treatment of calcite's dissolution rate from the literature in a closed system, particle batch reactor, with the alternative approach suggested by Truesdale (Aquat Geochem, 2015). We show that the decay of rate over time can be understood in terms of the evolution and distribution of reactive sites on the surface of …

If pore-fluids are only slightly supersaturated w.r.t. calcite, HMC is also unlikely to precipitate because HMC solubility increases with Mg content (Morse et al., 2006), making pore-fluids undersaturated or, at best, in equilibrium w.r.t. most HMC phases. Even if it precipitates, HMC is fated to dissolve because it is, like aragonite, a ...
