What determines whether a gemstone is precious or semi precious?

Is it the composition of the stone? cut ? or rarity?

The World Jewelry Confederation (CIBJO) is responsible for creating a definitive set of standards for the grading, methodology and terminology of diamonds, colored gemstones, pearls and precious metals.

The World Jewelry Confederation defines a precious gemstone as a “natural inorganic material, with the exception of metals, used in jewelry.

Semi-precious, is used  to describe gems that are not a rare stone, is now “misleading”.

Almost all gemstones can be defined as precious, except the pearl. It is also formed with organic matter rather than inorganic material. A protein called conchiolin* (a fibrous protein the forms the iridescent inner layers, as mother-of-pearl, in the shells of mollusks) is an essential part of the substance that forms a pearls’s nacre* (its what makes up the outer coating of pearls. It is strong, resilient, and iridescent.

Natural and cultured pearls are really quite unique in the gemology world.
