Organic Gemstones

Some gems are made from the biological processes of animals or plants. These come from the dead or living parts of a marine organism or tree gum. It can also be found in materials like dinosaur bones. Such gems are called organic gemstones. Some of these gems are obtained by farming nowadays, such as pearls.

After that gemstones are made by cutting them, or decorative items are made from them. Let us know which are those gemstones which come in the organic category.

1. Coral (Munga)

This organic gemstone formed as a branch-like calcareous framework by a microscopic marine organism known as the coral polyp. It is formed by the accretion of colonies of these tiny marine animals. The two main species are Corallium rubrum and Corallium nobile.

2. Pearl (Moti)

Pearls form inside a pearl oyster due to the concentric deposition of nacreous layers. Pearls are classified into two basic categories: natural and cultured. The term ‘synthetic’ must not be used with respect to pearls. Materials that simulate or look like pearls but do not have composition or structure are known as imitation pearls.

3. Amber (Kahraman stone)

Amber is the gum of a tree that dries and hardens over time. It is so hard and shiny that it is carved and used as a gemstone. Small parts of trees, plants, vegetation, insects, moths, mosquitoes, etc. can be seen very commonly in it.

4. Ivory

Ivory is basically dentine, which is the material that makes up the teeth of all mammals. From a commercial point of view, ivory can be the tusk of an elephant, a walrus, a narwhal, or the teeth of a hippopotamus. It is the elephant tusk that is most valuable.

5. Jet

Jet is a type of coal derived from wood that is transformed into gems due to extreme pressure and heat. It is a dark brown or black-colored gemstone with a metallic sheen. Sometimes it may mix with pyrite gemstones.

6. Tortoise Shell

As the name suggests, we get it from the turtles. The shell of certain species of tortoise is used as a gemstone in jewelry. It has yellow and brown spots; sometimes it also has white spots.
