Red and sapphire are valuable precious gemstones, resources are very scarce, and high-quality raw materials are even rarer. Therefore, people are always trying their best to deal with those poor raw materials to make them look more beautiful. In fact, the treatment methods for red and sapphire are far more than just heat treatment.
Except for heating, other methods more or less bring foreign matter into the interior of the gem, so it is no longer an optimization, but a real treatment. In accordance with the requirements of national standards, these treatment methods must be clearly informed to consumers when they are sold.
Here are the two most common treatment methods on the market to explain. I hope you can master simple identification methods and enhance your awareness of prevention.
Filling treatment is one of the most common treatment methods for rubies. The growth environment and physical properties of rubies determine their raw materials usually have more cracks. Fissures certainly have a great influence on the quality of gems. Sometimes, fissures even directly threaten the durability of gems, which is fatal to gems. Imagine how you would feel if the ruby ring you were wearing was knocked lightly and then snapped in half.
In order to cover up the cracks and to enhance the durability of the gemstones, people thought of filling the cracks of the gemstone with some glass with zero emissivity very close to the gemstone, usually high refractive index glass, because their refractive index is close to that of the gemstone. , The cracks are not obvious; and the glass also acts as a glue in the gem, which greatly enhances the durability of the gem.
Filled rubies are currently very common in the market. I personally think that this treatment method is good for the effective use of scarce raw materials. As long as consumers are clearly informed that they can buy precious gems at relatively low prices, it is a good thing. However, it is too bad for the filled and treated rubies to be sold as natural rubies, because the appearance of the gemstones before and after treatment is very different, and its value is indistinguishable from the natural rubies of the same appearance.
