Most limestones form in calm, clear, warm, shallow marine waters. That type of environment is where organisms capable of forming calcium carbonate shells and skeletons can thrive and easily extract the needed ingredients from ocean water.

Limestone is a sedimentary rock, which means it was formed from small particles of rock or stone that have been compacted by pressure. The water pressure compacts the sediment, creating limestone. The area around the Great Lakes, such as Michigan, Indiana, and Illinois, has a large amount of limestone.

Limestone and chalk are sedimentary rocks of organic origin derived from the accumulation of corals and shells in the sea. Limestone is soluble in rain-water, which, with carbon dioxide from the air, forms a weak acid. A region with a large stretch of limestone therefore possesses a very distinct type of topography.

It can be used as a food additive to provide calcium ions for strong teeth and bones. It can be processed as a useful raw material in the chemical industry. It can be used to neutralise acidic soil to allow plants to grow more effectively. This is mainly used for large-scale agriculture.

Clay Gemstones & Minerals

• Meerschaum: Meerschaum is a clay-like hydrous magnesium silicate.
• Celestine: Celestine appears as colorless, or pale blue, and is transparent to translucent, and has two directions of cleavage.

If your opal becomes ‘cloudy’ after a while, you are probably have an Opal triplet or doublet. This cloudiness happens when a triplet or doublet has been worn in water over a long period of time, causing the glue between the layers to deteriorate and allow water penetration.

It has a unique green appearance, so it is easy to tell the difference between the natural stone and the man-made version of Opalite. When the stone is cut into a cabochon and it begins to display a cat’s eye effect, that is when it is called Opalite Cat’s Eye.

Moonstone vs Opal stone – they have completely different chemical formulations. Moonstone belongs to the feldspar group, the most widespread minerals in the earth’s crust. To be precise, it is composed of orthoclase and albite. On the other hand, Opal is born from the water combined with silica.
