What are the advantages and disadvantages of platinum and gold? Which nature is more stable

Platinum: Platinum (PT), chemically more stable than **, and more expensive than **, is used to make high-end jewelry. The words "PT900" or "PT950" on the products in the jewelry store indicate that the platinum content in the jewelry is 90 and 95 respectively.

Purity The general purity of platinum jewelry is 95, while the purity of 18k gold is only 75. No metal can be completely pure, there are impurities, doped with other metals. Platinum has almost no impurities and is extremely pure, so it will not fade or change color, and will remain lustrous over time.

The pure white luster of platinum reflects the true brilliance of the diamond.

Rare Platinum is 35 times rarer than ** and can only be mined in very few places around the world, mainly in South Africa and Russia, as well as a few parts of Zimbabwe, Canada, South America. Every year, only 88 tonnes of platinum are made into ornaments, compared to 2,700 tonnes. The number of platinum ores is less, with a ratio of 1 to 10 mines.

Timeless Platinum's density and weight make it more durable than other jewelry metals. All precious metals leave scratches, and platinum is no exception. However, a scratch on platinum only moves the metal and does not reduce its volume, while a scratch on the platinum brings wear and tear, reducing the volume of the platinum.

If there are indeed visible scratches on the platinum, a qualified jeweler can re-polish it.

On the metal activity table, platinum is ranked ahead of gold. Of course, platinum is not as stable as gold. Platinum is a white metal, and gold is yellow. Gold is a universal storehouse, while platinum is mostly used in the jewelry industry.

The difference between platinum and ** is color, hardness, stability, etc.

1. Color

The most significant difference between platinum and ** is the color. Platinum is also known as white gold, from the name you can know that platinum is a white metal, we often use platinum white to describe the purity of love, simple and pure white is popular among young people, is a must-have item for today's fashion trend.

The color is golden yellow, and the higher the purity, the more yellow the color, as an indispensable member of the traditional wedding customs, regarded as a symbol of wealth, China's middle-aged and elderly people to buy.

2. Hardness

Each metal has a different hardness, from this aspect, the hardness of platinum is relatively hard, rings and other jewelry made of platinum metal, long-term wear is not easy to deform, and has the characteristics of hardness, platinum can also be inlaid with some precious gemstones and not easy to fall off.

The hardness of ** is 2-3, which is the lowest hardness in ***, so we can see that many ** jewelry that has been worn for a long time is basically deformed.

3. Stability

Platinum is highly corrosion-resistant, extremely stable at high temperatures, and electrically stable. It does not oxidize at any temperature and will always maintain its white metallic color, which is a valuable property that is loved by people, which is why many people call platinum "love metal", meaning love that will never deteriorate.

**The properties are also very stable, with strong corrosion resistance, not easy to oxidize with air, but the chemical affinity with sulfides is very strong, easy to adsorb sulfides in the air, so that the metal surface appears discolored.

Investment channels** are more favored

Because in recent years of market operations, most of them are accustomed to use ** to hedge credit currency risk. When the US dollar and the euro weakened for a time, the function of ** as a hedging tool was highlighted, and it gradually detached from the attributes of commodities.

But platinum's "luck" was not so good. First of all, the global economic recession has directly led to the restriction of platinum industrial production demand, which has led to a certain decline.

Secondly, the investment channel of platinum is narrow, and the market liquidity is relatively weak. It is understood that at present, the investment channels of platinum are very scarce, and there are not many banks in China that have opened paper platinum business, mainly concentrated in the Industrial and Commercial Bank of China.

The color will be different, and the yield will be different, and the ** will also be different, the ductility and chemical properties are different, but also have a very big difference, and the value is also different.

First of all, the degree of ** is relatively high, ** is also more expensive, and the color gives people a very yellow feeling, but platinum is mixed with some other ingredients, **will be cheaper than**, and the style is more diverse.

Platinum (PT) is a naturally occurring white precious metal. Platinum was discovered as early as 700 BC and has been considered one of the most noble metals in the more than 2,000 years of human use of platinum. In the mineral classification, platinum group element minerals belong to the natural platinum subgroup, including iridium, rhodium, palladium, and platinum.

PGE minerals are equiaxed, with very rare single crystals and occasional cubic or octahedral fine grains.

Platinum is one of the highest *** on the market, and its ** is even higher than **, and it has the reputation of the king of ***. Many investors have heard of the saying that platinum does not retain value. So as a rare metal, why doesn't platinum hold its value?

1. **** low.

The reserves of platinum in nature are very small, rarer than **, is the rarest in the world, the so-called rare is expensive, rarity is one of the reasons why platinum is higher than ****. Platinum is extremely dense and retains its original whiteness in extreme environments, and is often used to pair with diamonds. As a jewelry, this is a major advantage of platinum, but this feature also leads to platinum's melting point, energy consumption and processing technology are higher than **, and its ** is naturally higher than **.

Investors use high **** platinum, but the **** is very low, and the liquidity is poor, which is one of the main reasons why platinum does not maintain its value. Because platinum is mainly used for decoration, platinum has a high melting point and hardness, and it is difficult for general gold stores to detect melting platinum, so many gold stores do not support platinum.

2. Lack of monetary attributes.

The reason why it is regarded as a tool for value preservation and hedging by the common people is mainly because it is not only a symbol of wealth, but also an international currency with monetary attributes. Especially when inflation appears, people are more inclined to **** to avoid the shrinkage of wealth. Platinum is different, it only has the characteristics of ***, and does not have the nature of international currency, and the international recognition of platinum is also low, so the value preservation attribute of platinum is far lower than **.

Platinum is still a very rare metal, palladium more than platinum, I personally think that because of the car exhaust on the palladium instead of platinum, because the proportion of platinum and palladium is nearly half, the previous manufacturers used palladium is a lot more cost-effective, all with palladium, resulting in a large amount of palladium, now palladium ** more than half of platinum, in the future manufacturers may slowly use platinum instead of palladium, I personally feel that platinum at this price is still collectible.

It is a white precious metal with a relatively high density and strong ductility. The advantage is that it looks more beautiful, and it is cheaper, more cost-effective, and the production process is more troublesome, which is also a kind of ***. Of course I do, and I prefer platinum, and I think the quality of platinum looks better.

The color is different. Platinum is also called white gold, it is white and flawless in color, good gloss, and high highlights. **It is a golden hue, which also has good gloss and shine.

In terms of color, these two kinds of *** are easy to distinguish. Whether it is ** or platinum, the jewelry produced shows a high-end sense of color and exquisite style. Qualitatively different.

Platinum has high hardness, strong ductility, solvent resistance, corrosion resistance, and friction resistance, so it can be made into a variety of jewelry, and is not afraid of scratches, nor is it afraid of bumps, and is not easy to deform. It is not easy to fade and deteriorate when worn for a long time, and this quality is often used to set gemstones or diamonds, which is not only strong, but also can highlight the sparkle of the diamond.

With the improvement of people's living standards, people's surplus money has also increased. As a result, people want money to appreciate, and buying ** is a good choice. In addition, there are some people who also like to buy ** jewelry, such as the custom of buying "three golds" when they get married.

Difference Between Platinum and **.

1. Different colors: The most intuitive difference between platinum and ** is the color of metal. Among them, platinum, also known as white gold, is white in color, pure and simple, reflecting a sense of elegance and nobility.

The color of ** is yellow, and the higher the purity, the more yellow the color. **It is an element that often appears in traditional weddings, elegant and atmospheric, especially favored by middle-aged and elderly people.

2. Different properties: platinum has strong ductility, melt resistance, friction resistance, corrosion resistance, stable chemical properties, and high hardness, even if it is rolled into extremely thin platinum foil, the strength and toughness are much higher than other products; **It is a relatively soft metal, and the surface is easy to wear and deform.

3. Different hardness: the difference between platinum and ** properties is especially reflected in the hardness, due to the low hardness, so the jewelry created with ** is relatively simple; Platinum, on the other hand, is hard and is often used to make a variety of exquisite fashion jewelry.

4. ** and production are different: from the point of view of ** and platinum ** and value, the ** and value of platinum are higher than **. Because platinum is difficult to mine and the yield is low, the yield of ** is much higher than that of platinum.

5. Different production difficulties: platinum is the king of the world, with an annual output of only 5% of the highest quality, and tons of ore need to go through more than 150 processes, and it takes several months to refine a platinum ring weighing only a few grams. The ** is characterized by softness, so it is difficult to inlay a variety of exquisite styles.
