Identify platinum and K gold which is better
Platinum is the most precious scarce metal in the world. Its low-key and elegant temperament, versatile characteristics and timeless charm make countless people fall for it. Platinum is platinum (pt), a precious metal element, and K gold is a mixture.
What should we do when we are faced with not knowing if K Gold is good or Platinum is good? Now I will tell you about the advantages and disadvantages of each of these two jewellery, so that everyone has a rough outline in their hearts.
K gold is mainly made of gold, plus precious metals that are smelted together with other metals. Its advantages are high hardness, various styles and fineness, plus a variety of colors for everyone to choose from, a little more delicate. Fragrance.
Platinum is a very precious natural precious metal. The hardness is also the largest among the various precious metals currently known, so its style is also delicate and complicated. But relatively expensive.
Let's take a look at the characteristics, how to distinguish between platinum and K gold?
First, the composition
The metal composition of the two is completely different. Platinum is an element, and K gold is a mixture containing gold (au) and other small amounts of other metals. On the chemical element table, K gold is gold, and platinum is platinum. Platinum (pt) is more chemically stable than gold and is more expensive than gold and is used to make high-end jewelry. The “pt900†or “pt950†seen on the jewelry store's products means that the platinum content of the jewelry is 90% and 95%, respectively.
Second, the rarity
Platinum is 35 times more rare than gold, and it can only be mined in very few places around the world, mainly in South Africa and Russia, and in a few regions of Zimbabwe, Canada, and South America. Each year, only 88 tons of platinum are made into jewelry, while gold has 2,700 tons. The number of platinum mines is even less, and the ratio to gold mines is 1 to 10.
Third, durability
Platinum's density and weight make it more durable than other jewelry metals. All precious metals leave scratches, and platinum is no exception. However, the scratches on the platinum only move the metal, it does not reduce its volume, and the scratches on the gold will cause wear and reduce the volume of gold. If there is a visible scratch on the platinum, a qualified jeweler can re-polish it.
Platinum is a natural white precious metal, expressed in pt, usually silver gray. Platinum group metals are beautiful in color; strong in ductility; refractory, anti-friction and anti-corrosion; chemically stable at high temperatures. Therefore, they have a wide range of uses. Among the platinum group metals, the most familiar and used one is platinum.
Fourth, different in the jewelry mark
Platinum-colored jewellery containing more than 990 é“‚ platinum, usually with a "foot platinum" mark. The "P950" mark means platinum of 950 æˆ. White K gold should be marked with KK number. When buying platinum jewelry, you should ask the operator to issue an invoice. It is clear on the invoice whether it is platinum or white 18K gold. It is best to indicate the weight of the jewelry, so it is easier to claim in case of fraud. It can be seen that one of the "secrets" of choosing platinum jewelry is to recognize the Pt mark on the jewelry, in which the ring will hit the inner ring and the necklace will hit the buckle.

Five, the degree of difference is different
Platinum is the rarest metal in the world. Platinum has been produced since ancient times. It is only one-thirtieth of gold. Platinum has a high melting point. To extract 1 ounce (31.1 grams) of pure platinum, 10 tons of ore is needed. That is to say, one piece is made. For a three-gram platinum ring, use 1 ounce of platinum ore. The platinum mining process is very complicated. Platinum requires 150 processes from ore to platinum ingot. Over 8 weeks, with the increase in platinum demand, South Africa's most platinum mines operate 24 hours a day, and it is difficult to meet the growing demand in the platinum market. Platinum is currently the most expensive of all jewellery precious metals, and some unscrupulous merchants have confused the concept of K gold and platinum for profit.
Jewelry is good or bad. When you finish reading the above text, is it good for K Gold or Platinum? Does it have your own answer? In fact, if you really want to give a good one about K Gold or Platinum The standard answer, who can really define it? So for the good or the bad between them, we can know it by weighing it on the balance in our own mind.
