Zveřejněno na podle Kingjy

The color of the gemstone must be beautiful, and it must be bright to look good. The flares of gems are not strong, which is also related to inclusions (inclusions). During the formation process of gems, they will capture surrounding minerals and water vapor, and produce bubbles, liquids, solid minerals and other inclusions. Inclusions are generally referred to as “impurities” nebo “blemishes.”

When choosing a gemstone, samozřejmě, the less inclusions, the cleaner and the more transparent, Čím vyšší je hodnota. But in fact, natural gemstones are rarely completely clean and often have flaws, and these flaws have even become gem ID cards. Completely transparent and flawless gems (rubín, smaragd), the suspicion of synthesis is quite large.

Among various inclusions, cracks are the most taboo. During the heat treatment of gemstones, the cracks caused by the rapid cooling transition of the temperature, or the cracks caused by the vibration of the gemstone cutting and grinding, and the missing corners of the gemstones colliding with each other after the cutting and grinding process (the sharp bottom and the waistline are most likely to collide and produce small gaps) Wear marks with faceted ridges will reduce the value of the gem.

Však, inclusions are not necessarily deductible for gems. Například, some inclusions can cause a cat’s eye effect on gemstones, and for crystals that are very popular in recent years, the more the content, Čím vyšší je cena. Natural inclusions can also be used to verify the origin of gems, such as rubies produced in Burma, which contain minerals such as gibbsite, rutile, and calcite. Some jewelry collectors particularly like red sapphires that have not been heat-treated. Appraisers can observe the inside of the gem and find that the natural minerals are completely crystallized and have not been melted. This means that the gem has not been heat-treated and the price will be three higher than that of heat-treated red sapphires. To 50%.

The inclusions and flaws of gemstones can be known at a glance through identification. Například, the GIA certificate will mark the flaws of the diamond, which is very detailed. The exact same flaw is impossible, so it is easy to identify the authenticity of the diamond.
