Because of the variety of types, garnets are often sold under commercial names in the gem market, and the price varies greatly. This book introduces the more common garnets in the gem market. The following are the more common types in the market.

Almandine: It is called noble garnet on the market. It is the most common type of garnet. It is usually dark red or deep purple red. Although it is called noble garnet, it is popular and inexpensive. Most of the garnets fall into this category.

Magnesia garnet: also known as rhodolite. The English name Pyrope is derived from the Greek word “fire”. It is named after the red color of magnesia garnet. Sometimes it is also called CapeRuby. Because the color is the closest to ruby, it is easy to be confused with ruby. In passato, it was also regarded as ruby. The difference between the two lies in their refractive index and specific gravity. Ruby double refraction and garnet single refraction are easy to distinguish. In the 18th and 19th centuries, magnesia garnet was very popular in Europe.

Pink Garnet: A garnet with both almandine and magnesia garnet. The color is rose red to purplish red. The name of Rhodolite is derived from the Greek rose. It is widely loved for its beautiful color.

Spessartine garnet: The first spot was discovered in the Spessart region of Bavaria, Germania. The gorgeous color from yellow orange to orange is its most attractive feature. There is a garnet called Hollandine on the market. , Is a spessartine garnet containing a small amount of magnesia garnet. Dutch stone was first discovered in Africa by Dutch explorers. In order to pay tribute to the Dutch royal family, it was called Dutch stone. Spessartine and yellow-orange topaz are similar in color, and the two can be distinguished by the double refraction of corundum-type topaz and the single refraction of garnet.
