As long as there are diamonds with certificates, more than 20 points, color, clarity, size, will be clearly marked. If you are such a large diamond with 46 points, you must detect it. The certificates are marked ~~ ~~ First, when you buy a diamond, you must be optimistic about the level. If you buy it, it is worth it. ~~ third, the level of 46 points is generally 30,000 to 40,000!

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.
