千万别试!这5种最不靠谱的翡翠鉴定方法... 很多翠友在购买翡翠时,会向朋友或者商家打听很多鉴定翡翠的方法。其实有些方法是不科学的,在鉴定过程中,甚至会对翡翠造成损坏,以下这些方法就别尝试了! 1.将头发缠在翡翠上烧 这个方法似乎还流传得挺多,就是用头发丝缠在翡翠上,用打火机烧,断了就是假的,烧不断就是真的。 小学课程中就说过火焰分内焰、外焰,外焰的温度比内焰高很多,翡翠导热性再好也阻拦不了外焰秒杀头发的温度。 2.手感较凉的就是真翡翠 还有说法是真货翡翠放在手上会比较凉,仔细想想就知道凉来作为鉴定依据也是很不充分的,凉是我们的触感,这种触感会因为人手温度的变化而产生变化。 3.可以划玻璃的就是真翡翠 很多人会告诉顾客翡翠的硬度很高,可以划动玻璃的就是翡翠。 玻璃是石英这个应该是众所周知的,石英的摩氏硬度为7,而翡翠的硬度是6.5——7。玻璃每个方位硬度一致,翡翠的解理面硬度差,在划动玻璃过程中,可能会受到一定程度损坏。 有很多硬度较高的宝石都可以划玻璃,所以翡翠是否可以划玻璃不能作为鉴定依据。 4.敲击声清脆的就是真翡翠 还有一些人用翡翠敲击声来判断真假,其实敲击的清脆声不仅跟翡翠密度有关,跟石纹也有关,有石纹的A货翡翠敲击声也很沉闷。像翡翠戒面、镶嵌品等来说,这个方法是不可行的。 5.开水煮翡翠鉴定翡翠 这也是曾经在网上流行过的一个翡翠的鉴别方法,说等水烧开了,把翡翠放进去煮几分钟。如果水变了颜色,就能肯定翡翠这是经过染色处理;如果水面上有漂浮着的胶状体,那就是经过填充处理的;而真正的天然翡翠怎么煮都没关系。 且不说这样是不是真的能辨认真假,这种破坏性的鉴别方法本身就有很大的风险。翡翠最忌讳温度骤变,把翡翠突然放进煮沸的水中,很有可能让翡翠发生破裂或者内部出现裂纹,影响翡翠的品质。 建议大家在购买翡翠的时,一定要多看,最重要的是选择信誉好的商家购买。像翡翠王朝保证所售货品均为正品,可以七天无理由退换货,且所有货品支持检测,在现代技术下,翡翠是很容易鉴定的。  Do not try! The five most unreliable jade appraisal methods ... When many jade friends purchase jade, they will ask friends or businesses for many ways to identify jade. In fact, some methods are unscientific. In the process of identification, even the emerald will be damaged. Please do not try the following methods! 1. The hair wrapped in jade on the burning This method seems to be circulated too much, that is, with hair filaments wrapped around the jade, with a lighter to burn, broken is false, burning is true. In the elementary school curriculum, it was said that the flame is divided into inner flames and outer flames. The temperature of the outer flames is much higher than that of the inner flames. No matter how good the thermal conductivity of the jadeite is, it cannot stop the temperature of the outer flames to kill the hair. 2. The cooler feel is the real emerald There are arguments that the real thing is that jade will be cooler on the hand, and if you think about it, you will know that it is not sufficient to use it as a basis for identification. Coolness is our tactile sensation, and this touch will change due to changes in the temperature of the human hand. 3. It is true jade that can plan glass Many people will tell customers that the hardness of jadeite is very high. It is jade that can move the glass. The glass is quartz, which should be known. The quartz has an Mohs hardness of 7, and the emerald has a hardness of 6.5-7. The hardness of each azimuth of the glass is the same, and the hardness of the cleaved surface of the jade is poor. In the process of wiping the glass, it may be damaged to some extent. There are many gems with higher hardness that can be classified as glass, so whether Jadeite can be classified as glass cannot be used as an identification basis. 4. percussion is crisp emerald Some people use the jade percussion sound to judge the true and false. In fact, the crisp sound of the percussion is not only related to the density of jade, but also related to the stone pattern. The rock sound of the stone material A jadeite is also boring. Such as jade ring, mosaics, etc., this method is not feasible. 5. Open boiled jadeite identification jadeite This is also an identification method that was once popular on the Internet. He said that when the water boiled, put it in and cook it for a few minutes. If the water changes color, it can be sure that the emerald is dyed; if there is a floating gel on the water, it is filled; and it doesn't matter if the real natural jade is cooked. Not to say that this is not really true or false, this destructive identification method itself has a great risk. The sudden change of temperature in jade is the most taboo. Putting jade into the boiled water suddenly makes it possible for jade to break or crack inside, affecting the quality of jade. I suggest everyone in the purchase of jade, we must see more, the most important thing is to choose a good business reputation to buy. Like the emerald dynasty, guaranteeing that all the items sold are authentic, it can be returned in seven days without reason, and all products support testing. Under modern technology, jade is very easy to identify.
