The brand must not fake it. First, the print seals are clear and not. Then look at the identification certificate. Compared with the total weight of the real object, the stones are right, right? The cargo is better than 3, and I think it is okay.
If it is less than 10 points, it is originally a jewelry, which does not matter whether it is true and false; about 20 points, there are national inspection certificates to check for you, more than 30 points, there are international certificates and national inspection certificates. Not fake. Of course, it is best to come and ask before starting.

The naked eye observation method: Real diamonds generally only exude blue light and orange light, and imitation products are prone to colorful light; really diamond edge horns sharply, and the corners of the imitation products are prone to suffer Dordling, relatively blunt. 2. Harbin Qi test method: Real diamond heat transfer ability is good, and the heat is scattered fast. You can breathe on the diamond. If the water and gas disappear immediately, it is generally true, and the water and gas on the imitation products generally stay for a few seconds to disappear. 3. Wipe test method: Really diamond hardness is high. If you rub the paper on the surface of the diamond, there will be no scratches on the diamond, and the imitation products generally have obvious scratches. 4. Drop test method: drop of water on the diamond. If the water droplets can keep the spherical shape for a long time, it is generally real diamonds, and the water droplets on the imitation products generally spread out quickly. 5. Line testing method: Diamonds have a high folding rate. Draw a line on the paper and place the diamond on the front of the straight line. Generally, real diamonds can not see the straight line underneath. If you can see it, it is generally imitationnYou can also go to relevant stores for identification, which is more secure!nHopefully my answer is of help to you!n1 morenBleak

(一)目测方法：标记：每件首饰都应刻有化学成份印签，如(pt900)(pt750)字样，凡是有“pt”开头的印签，均是铂金饰品颜色：铂金呈锡白色， That is, white and gray, shiny (2) Instrument detection: test hardness: platinum hardness is 4--4.5 degrees, harder than gold, silver Nail scratching and testing density: The density of platinum is extremely large, and the hand is sinking. The test density of the use of static water mechanics should be 21.43g/cm cubic cubic burning: the melting point of platinum is as high as 1773 degrees, and the platinum is placed on the alcohol or electric furnace. Burning, the color does not change the acid test: the platinum chemical properties are stable, insoluble in ordinary acids. Platinum is drawn on the test gold stone. In the hypoxic hydration bottle, the bubbles are immediately produced by hydrogen peroxide. The platinum after the reaction is not damaged. It can still be used
of the seven characteristics of platinum
platinum, because its unique character has always been The precious metals, which are regarded as precious, have strongly advocated the International Platinum Association in recent years, making it increasingly occupying an important position in the wedding ring.
In the ancient Egyptian era 3000 years ago, platinum had been widely used by people at the time. Archaeologists have discovered a platinum -made text on the coffin of Egyptian priests. After a long time, they can still be perfect and not lose their original luster, which fully proves the lasting and stability of platinum. After the first diamonds were dug out of the Kingsley mine in South Africa, platinum was very different.
This year, the Italian Platinum Association launched a series of new types of wedding matching, and proposed seven characteristics of platinum, indicating that platinum works are the best choice for becoming precious metals.
1. The highest purity
. 95 % of the pure platinum in the alloy of platinum and 75 % gold with a gold of 18K. A platinum jewelry has a higher purity than gold jewelry.
2. The rarer
The 140 tons of platinum in the world each year, while the annual production of gold is 3,300 tons.
3. Only the skilled craftsmen can make it. The melting point of platinum is higher than that of gold, so it is more proficient in the technical requirements of workers.
4. The most stable
. Platinum is the strongest metal with the strongest resistance to acid, alkali, high temperature, etc., and will not fade or change color. Platinum ring does not change
.
5. Good luster and ductility
Platinum has natural white and gloss, which will not affect the color of the gem, and it can make the gemstone release glory and "fire". Processing.
6. It will definitely not make the jewelry a allergic reaction.
