In the field of collection, gem is a relatively broad concept, and an important part of it is mineral crystal gem. There are thousands of natural minerals in the world, but only a few dozen can really be used as gems. Gems require strong wear resistance, so the hardness is generally higher. Gems should also be as pure as possible, without impurities and cracks, with bright luster and beautiful colors. Many conditions determine the scarcity of precious stones. High-quality gems are therefore expensive.
In order to facilitate the identification of gems, people make the grade of gems as convenient as possible. The bigger the particle, the higher the value of the same grade gem. However, the price increase is not proportional to the increase of gem weight. When a gem increases in a grade range, its unit price will double, which is the premium principle of gems. Only precious stones are priced according to the premium principle. It is undoubtedly a good choice to invest in this kind of gem collection, which is worthy of collection level and will always appreciate and preserve its value.
Other beautiful stones are also classified as gems. Although these stones are not mineral crystals, collectors are interested in them because of their hardness and beauty, such as jadeite. High-quality jadeite is not inferior to crystal gemstones, but its elegant and subtle features are more favored by China, Japanese and other oriental nations. Almost everyone who loves beauty, especially ladies, yearns for beautiful jade rings, brooches and bracelets.
Out of the pursuit of beauty, people also classify some petrochemical organic substances with fine structure, bright color and hard texture into the category of gems, among which beeswax, amber, coral and pearls are the most prominent. People in China often refer to precious jewelry as "jewelry", which may reflect the importance attached to pearls.
Because of its beauty and scarcity, precious stones have been loved by China royal families, foreign royal families, dignitaries and wealthy businessmen since ancient times. They searched for treasures all over the world and became the largest gem collection institution, leaving the richest treasures and countless bizarre anecdotes for people today. These treasures are even the flesh-and-blood testimony of many important historical events. In the face of these rare treasures, anyone will be shocked by their magical magnificence, and then sigh the magical power of the creator.
With the development of modern science and technology, great changes have taken place in gem industry from exploration, excavation to processing and other fields. Advanced technology has greatly increased the output of precious stones, and precious stones are no longer the exclusive luxury of a few people. With the progress of society and the improvement of people's living standards, precious gems have since entered the homes of ordinary people.
Gem industry is highly professional, and the gem itself is more convenient to measure, so it is easier to standardize the price evaluation, which is significantly different from other antique works of art. Whether it is mineral crystal gem, multi-mineral aggregate gem or organic gem, it is increasingly favored by people, and collecting gems has become a fashion trend. Numerous examples show that investing and collecting high-quality gems is an excellent channel for appreciation or preservation. With the further improvement of people's living standards, the growth trend of gem industry will develop steadily.
