Any gemstone that is not a diamond, ruby, sapphire or emerald is considered a semiprecious stone. This is not to say these gems are less valuable or desirable than precious stones, but in most cases, they are considered “semi” precious simply because they are more abundant. In fact, this terminology was started in the West for marketing purposes and is no longer in favor—now it is more common to refer to semiprecious and precious stones as “gemstones.”

A semi-precious stone is also known as a gem or gemstone (also a jewel, a gem, a precious stone), which is a portion of mineral, which, in refined and cut form, is used to create jewelry or other embellishments. There are also organic resources or precise rocks that are not minerals (for example jet or amber) that are also used for jewelry and would also be considered to be gemstones, as well.

What are gemstones?

A gemstone is a precious or a semi-precious stone used in jewelry. Gemologists identify gemstones. They label gems in the arena of gemology using practical language and their features. A gemologist uses the gemstone’s chemical arrangement to classify it. For instance, diamonds are made of carbon (C). Many gems are categorized by a crystal system because they are crystals. Gemstones are classified into different varieties, species, and groups. They are also characterized in terms of dispersion, hardness, specific gravity, refractive index, luster, fracture, and cleavage. Flaws in a stone are known as inclusions.
