What does the term conchiolin refer to in gemology?

Conchiolin is an organic component found in certain gemstones, particularly in the structure of materials like pearls and some types of shell. It serves as a binding agent for aragonite, a mineral form of calcium carbonate, helping to create the layered structure characteristic of these materials. This makes it critical to the overall formation and integrity of pearls and similar organic gemstones.

Understanding conchiolin's role is essential in gemology, as it contributes to the physical properties and aesthetic qualities of the gemstones in which it is present. Its presence can also affect the gemstone's luster and resilience. This context establishes the significance of conchiolin beyond just a simple identification, illustrating how it plays a vital role in the characteristics of certain gem materials.
