Cleaning mineral specimens: a guide for mineral collectors ...

A last warning, if you are removing calcite from a specimen, do not dissolve all calcite. Often it may be the only thing holding the specimen together. A little calcite can provide a nice contrast and make it more aesthetic. In the case of the spinel crystals from the Limecrest Quarry, there are often alternating layers of spinel and calcite.

Gaspeite Gemstone Information - GemSelect

Gaspeite is a member of the calcite group of minerals, which includes several other carbonates with similar physical aspects, of which calcite is the most well-known. Most calcite matter does not form with clean, transparent gem-quality material, thus the lack of gemstone value. There are not many related gemstones on the market today, although there are many that are similar in appearance.

Graphite - Wikipedia

Graphite (/ ˈ ɡ r æ f aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.It occurs naturally in this form and is the most stable form of carbon under standard conditions.Under high pressures and temperatures it converts to diamond.Graphite is used in pencils and lubricants.

University of Minnesota's Mineral Pages: Calcite

Unlike calcite, gypsum does not react with dilute acid to form bubbles, although if the gypsum is crushed into a powder it may simply dissolve. Quartz: Quartz crystals and masses may have the same luster as calcite, but quartz does not exhibit cleavage and will not react with dilute acid. Quartz is also much harder than calcite.

Avoid exposing lepidolite to bleach or sulphuric acid. Lepidolite can be cleaned using warm, soapy water. Wipe down stones using only a soft cloth and be sure to rinse well to remove any soapy residue. Always remove any lepidolite gems or jewelry before exercising, playing sports or engaging in vigorous chores.

Malachite -

Some definitions of minerals give them as inorganic materials, however both diamonds and graphite are considered minerals, and both are primarily comprised of carbon, which would make them organic. So this leads me, as an engineer, to believe that mineralogists do not have a good, precise definition of a mineral, but rather a loose definition.
