What gem is known for having the widest range of colors?

Garnet is renowned for its impressive spectrum of colors, making it unique among gemstones. This mineral group encompasses a variety of species, each associated with specific elemental compositions that lead to different colors. While garnets are often recognized in their red form, they can also exist in a broad range of hues including green, orange, yellow, purple, pink, brown, and even colorless. Additionally, garnets can exhibit color changes and come in vibrant compositions such as tsavorite (green garnet) and spessartite (orange garnet).

This remarkable diversity is a result of the different chemical elements that can substitute for one another within the garnet structure, thereby allowing for such a wide array of colors. This characteristic sets garnets apart from other gems, highlighting the richness of color they possess.
