For gems, as a "loyal fan", everyone must be able to talk about it, the head is the road. However, the following common misunderstandings, can you be sure that you have no plans?
Gem is a treasure, just a plaything for the rich.
In fact, there are many types of gems. High-end gems like diamonds, rubies, sapphires, emeralds, and natural value are not expensive, they can be bought and bought. However, some medium and low-grade gems, such as crystal, topaz and olivine, are very rich in variety and color, and the price is very close to the people. If you like, you can buy and decorate yourself. Don't forget, only the first thing that satisfies the "beauty" is that all the "rare" and "precious" have value. Of course, if you can afford to buy high-value gemstones if your financial resources permit. First, high-value gemstones tend to have higher “face valueâ€; secondly, high-value gemstones have higher investment value and greater appreciation potential.
Gems should be crystal clear, as long as there are obvious impurities inside, they are all "junk goods".
Crystal clear gems, I think everyone likes it. However, is it not a gemstone that does not reach the crystal clear effect? ​​Is it not a good gem? We often hang on the "pigeon ruby" and "corner sapphire", why are they so noble, so beautiful, except for their color In addition to the purity of the original, there is also an important reason, that is, they often have some very fine inclusions inside, which block the passage of light to a certain extent, forming a diffuse reflection effect inside the gemstone, thus forming a "perfect The color of the dead end. It avoids the "dark surface" effect formed by insufficient internal reflection of light when the interior is pure.
In addition, the impurities inside the gemstones are also a testimony to the gemstones that have undergone millions of years of baptism in nature. They are also a proof of the origin of many precious gemstones, proof of high value (such as Burmese rubies), therefore, the impurities inside the gemstones should not be underestimated.
Also, gemstones such as emeralds are almost impossible to have no impurities inside. If you have to be nitpicking, then go play crystal. The interior of the crystal is generally very pure, but what is the use of this?
The gems are very hard, no one is afraid
The gemstones we can see have experienced the geological effects of nature for millions of years and are often very hard. Especially the king of gems - diamonds, is the world's harder material. However, substances with high hardness are sometimes brittle. For example, diamonds are easily broken if they are hit hard. Not to mention other gems, such as emeralds and other gemstones with more internal cracks, are more fragile.
In addition, the main component of diamonds is carbon. If you encounter an open flame, it will be "dusty and smoked." Many gems, in the case of severe temperature changes, may be broken due to thermal expansion and contraction. Although the gems are hard, the heart is actually fragile.
Gems must be 100% natural
The concept of "natural" gemstones has long been popular. If the gemstone can be mass-produced by hand, what is the rarity? This is true, but the naturalness of the gem, in addition to natural production, includes the naturalness of color and other characteristics. For example, ruby, the naturally produced ruby, is not bright and bright, and it is difficult to meet the needs of consumers. Then there was heat treatment technology, which was to put the ruby ​​into a special high temperature environment and heat it to improve the color and transparency of the ruby. This method, which we call "heat treatment", is accepted by the market and the industry, as long as the consumer is clearly informed before the sale.
For example, emeralds are often difficult to cut and polish because they are naturally rich in cracks. Therefore, a method of injecting a colorless oil into the interior of the emerald is produced to improve the clarity and durability of the emerald. These very mature gemstone treatment methods, which we call "optimization", are acceptable. It is also with these means that we can see more beautiful gems.
However, there are some means, such as filling the red rubbish inside the cracked ruby, or pickling the emerald, or emphasizing the emerald with colored oil, which fundamentally changes the characteristics of the gem. We call it "handling." After these "handling" gems, we must "avoid away."
