The total weight of emeralds carried by the "Nuestra Senora de Atocha" in several chests was estimated to be around 6070 pounds (2732 kg), equivalent to 135,000160,000 carats. Out of this only around 6 pounds ( kg) of emeralds have been rediscovered, equivalent to about 13,500 carats. This represents about 6,000 uncut rough emeralds.
Aside from marine gastropods, and discounting iridescent colour, which may be structural, the best examples of distinctly blue or green molluscan shell pigmentation in bivalves and land snails are found in species with a coloured periostracum ( Fig. 2C, L, M) or organic sheets overlying the inside of the valves ( Fig. 2A). It is ...

A fossilised compound coral colony occurs in the rock. The rock could come from the Mumbles region, but in all probability, is an example of Cork Red Marble from Ireland. 53 Cork Red Marble was very popular from the 1830s until the 1920s and had the trade name of Victoria Red Marble.

The living coral that turned into the Petoskey stone thrived on plankton that lived in the warm sea. Calcite, silica and other minerals have replaced the first elements of each cell. Each separate chamber, then, on each Petoskey stone, was a member of a thriving colony of living corals. For that reason the Petoskey stone is called a colony coral.
Limestone. Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Most limestone is composed of skeletal fragments of marine organisms such as coral or foraminifera. Limestone makes up about 10% of the total volume of all sedimentary rocks.
Mineral engineers may drill core samples and conduct surface surveys, searching for specific compounds and ores. Ground Penetrating Radar (GPR) is a geophysical method that has been developed for shallow, highresolution, subsurface investigations of the earth.
Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement for preventing and treating osteoporosis. (NCI04)
The principal component of limestone is the mineral calcite, but limestone frequently also contains the minerals dolomite (CaMg(CO3)2) and aragonite (CaCO3). Pure calcite, dolomite, and aragonite are clear or white. However, with impurities, they can take on a variety of colors.

Definitely stay away from things like Calcite which will gradually dissolve in the tank and change the ph of the water or poison your fish. Also, minerals can be damaged by food or fish "droppings" that land on them. I would think "gemstone" minerals like beryl, or sapphire would do well.

Composition and distribution. Coquina is composed mainly of the mineral calcite, often including some phosphate, in the form of seashells or dating from the Devonian period through to the much more recent Pleistocene epoch are a common find all over the world, with the depositional requirements to form a coquina being a common thing in many marine facies.
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite. A rock is an aggregate of one or more minerals, or a body of undifferentiated ...
