The durability of gems is determined by their stable physical and chemical properties, but this condition can be appropriately relaxed for certain gems, such as organic gems and marble.

(3) Rarity
Although there are more than 3,000 kinds of minerals found in nature, there are only more than 230 kinds of gemstones that can be used as raw materials, and there are only more than 20 kinds of main high- and mid-grade gemstones in the jewelry market. Mineral rocks must have some specific conditions to become gems. Gems are the essence of many mineral rocks. The rarity of gems includes the rarity in variety and rarity in quality. Such as demantoid demantoid which affects the price due to its rarity. Due to the rarity of quality, such as emeralds, the emeralds produced in the Urals can weigh several kilograms, but they can rarely reach 1 ct when processed into high-quality products.

It should be pointed out that as a gemstone or a variety of gemstones, it does not necessarily require it to be the best or the most outstanding in terms of beauty, durability and rarity. Often one or two of its outstanding aspects can be regarded as gems, but there will be differences in value. Till exempel, bärnsten, although its hardness is not very high, Mohs hardness is only 2-3, its durability and abrasion resistance are not strong, but they are still with its deep cultural background, special honey yellow, brown red and other colors, and soft luster And special inclusions attract people and become a precious gemstone variety. Till exempel, some red sapphires with starlight effect, even if their color is not very good, if their starlight effect is obviously perfect, it will be valuable. Dessutom, the value of gemstones is not only related to their own quality, but also affected by factors such as time, region, culture, aesthetic concepts, resource reserves, and the economic environment at that time.
