What is the difference between platinum and white gold What is the difference between platinum and w

What is white gold, what is platinum, and what is the difference?

1: The official interpretation of the Platinum Guild International: Platinum = Platinum = Platinum = PT ≠K Platinum.

2: [Platinum] (PT for short) is a naturally occurring white ***. The state stipulates that only jewelry with a platinum content of more than 850 can be called platinum jewelry and must bear the PT mark.

Platinum jewelry usually bears the purity mark of PT850, PT900, PT950, or PT990. Therefore, there is no such thing as 18k or 750 (i.e. 750 purity) in platinum jewelry).

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

4: The common name of platinum is platinum, platinum gold is pure white, and the reserves of platinum in nature are scarcer than **, so it is more expensive than **. Platinum can make the white diamond maintain its original color, and it is very strong, it is the best material for setting diamonds, and it is the diamond that makes platinum the superstar of jewelry.

In China, most of the colors used in jewelry inlay are PT950 and PT900, and PT900 is the most commonly used.

5: Only platinum can be called "white gold", but not all white metals are platinum. When buying platinum, look for the PT logo.

In ancient Chinese, "platinum" means silver. The so-called K platinum in the market is actually an alloy of gold, nickel, copper, zinc, or gold and silver, or an alloy of gold, silver and copper. It also includes alloys of gold and palladium, which are often used by Taiwanese masters.

Its code name WG (whitegold) means white gold. In the early days, 226 (6 percent gold, 2 percent palladium, and 2 percent copper) was used to represent white gold containing pure gold 600 1000, which is commonly known as "material", which means silver-white metal containing gold, rather than nickel alloy (nicklealloy) plating without gold. Generally, foreign stamps are commonly used WG585 (14K), WG750 (18K) or only numbers to represent the gold content.

White gold has good reflectivity and is not easy to lose its luster, and before platinum and palladium were used in large quantities in the future, white gold was the silvery-white metal mainly used to set gemstone jewelry.

Platinum:

It is a natural white ***. Platinum is mined annually at only one-twentieth of the highest level, and an ounce of platinum takes five months to extract from 10 tonnes of platinum ore. Domestic platinum jewelry usually contains 990% pure platinum and is marked with "PT990" or full platinum.

Platinum:Yes** appears white after adding certain alloys. It contains only 75% of the maximum of **. White gold cannot be marked with the PT mark, but can only be marked with ** and purity according to its purity.

In the international market, platinum is much more than and is the highest of all. In addition, some white jewelry may also be made of silver or have white metal plated on its surface, which may reveal its original appearance over time. Although platinum is sometimes commonly referred to as white gold, in a strict sense, it should be called "platinum", and platinum is the meaning of the chemical element platinum.

Therefore, the purity, rarity, durability and natural white luster of platinum are all incomparable to white gold.

In fact, only platinum can be called "white gold", not all white metals are platinum.

Platinum, a *** element, commonly known as "white gold", also known as pure white gold, pure white gold or real white gold. But these titles are not reasonable and can easily be confused with white gold.

Compared to platinum, platinum is of course worth more, and it's not a little higher.

Difference Between White Gold and Platinum.

1. Thousands of pure gold.

Refers to pure gold jewelry with a metal content of 99 9, engraved with 999 or 1,000 gold character seals.

2. Pure gold. Refers to pure gold jewelry with a gold content of 99%, engraved with 99% or pure gold.

k**。Refers to jewelry containing 75 ** ingredients, and the remaining 25 are other ***, engraved with 18k or 750 marks.

K white gold. Refers to the ** jewelry containing 75 ** ingredients and the color is white, and the remaining 25 are other white ** genera, engraved with 18K or 750 marks.

5、pt900

Refers to platinum jewelry containing 90 platinum, the remaining 10 for others, platinum and palladium content of 950, and the imprint is pt900.

Refers to jewelry containing 95 platinum components, the remaining 5 are others***, and the imprint is pt950.

The metal composition is completely different, and on the list of chemical elements, one is gold and the other is platinum

Platinum, also known as platinum, its English is platium, generally its abbreviation PT as the code. The gold jewelry sold by merchants marked with 18k platinum or 18kwg is a white alloy with 25% palladium or nickel added to it, which is actually a kind of K gold, and its **content is 75%.

What is white gold, what is platinum, and what is the difference?

Summary. Dear, wait a minute, for you to find out: what we usually call white gold is 18K platinum (gold with 75% gold content) The chemical element is AU, and platinum is called platinum, and the chemical element is PT.

Both of these are very scarce***, and there is no good or bad one. Let me talk about platinum PT from the respective metal properties: generally use 99% or 95% or 90% three contents, the higher the purity, the smaller the hardness, so the high content is generally plain circles for modeling, not for gem inlays (easy to lose gems).

95 and 90 content, often do inlays. One of the benefits of platinum is that it is white no matter how it is worn. Also, platinum has a much higher melting point than 18k white gold.

18k white gold: It is the most common inlay gold in jewelry at present, and it is also the most commonly used ratio by big brands, with good processing performance and moderate hardness. Most of the 18k white gold is plated with a layer of rhodium to increase its white color (generally the natural color of 18k white gold is slightly yellow).

What is the difference between platinum and white gold.

One of the benefits of platinum is that it is white no matter how it is worn. Also, platinum has a much higher melting point than 18k white gold. 18k White Gold:

It is currently the most common inlay gold in jewelry, and it is also the most commonly used ratio by big brands, with good processing performance and moderate hardness. Most of the 18k white gold is plated with a layer of rhodium to increase its white color (generally the natural color of 18k white gold is slightly yellow).

The platinum market** fluctuates around $340 per gram. In the domestic market, 18k platinum is about 240 yuan, and the international brand 18k platinum can be sold for 1,000 yuan a gram, but now the brand sells 18k platinum will not be calculated by grams, and it will increase labor costs, processing fees, styles, etc.

It's normal to not be able to tell the difference between platinum and platinum, because they're just the same thing. It's just that now many merchants will call platinum gold platinum in order to sell platinum gold. But according to state regulations, only platinum can be called platinum.

If you want to distinguish whether the jewelry you buy is white gold or platinum, it is very simple, look at the inside of the jewelry to see if there is "PT or platinum", they are like platinum ID cards, if there is, it is real platinum jewelry.

There is no difference between platinum and platinum, only platinum can be called platinum, so the two are the same thing. Platinum is a natural white color***. The state stipulates that only jewelry with a platinum content such as 850 or more can be called platinum jewelry and must bear the PT mark.

When buying rings, you will encounter platinum, platinum and **, and young people generally like to buy platinum and platinum. However, we can't tell the difference between the two. Generally speaking, only real platinum can be called white gold, and the two are the same material, there is no difference.

However, nowadays, everyone basically calls 18K white gold white gold, and gold with a metal platinum body called platinum.

Therefore, the white gold that is often referred to now is actually white gold, which is a color in 18K gold, and is an alloy, which is marked as AU750. Whereas platinum is a natural white color***, the bridge fluid usually bears the purity mark of PT850, PT900, PT950, or PT990.

The difference between platinum and white gold is:**Different, different composition, different color, different hardness, different markings.

1. **Different

Platinum is a natural metal, the stock is small, so it is more expensive, at present, PT999 platinum per gram is about 360 yuan, PT990 platinum is about 355 yuan per gram, PT950 platinum ** is about 350 yuan per gram.

At present, the ** of 18k white gold is only about 270 yuan per gram, even if the process cost is calculated, the maximum is about 300 yuan per gram.

2. The composition is different

White gold is a natural white metal, and the substance is relatively pure; And 18k white gold is an alloy mixed with other metals.

3. The color is different

Although the color of 18k white gold is similar to the color of platinum, there are still some differences in details, the white of platinum is natural off-white, while the color of 18k white gold is formed by electroplating and polishing, so the white is more eye-catching.

White gold is a natural color that does not fade easily and can remain unchanged for a long time; And 18K white gold is formed by polishing, and it may change color after a long time.

4. The hardness is different

White gold has a higher hardness than ordinary **, while 18k white gold, although it contains 75% **, is harder than white gold because of the addition of other metal elements.

5. The markings are different

The platinum jewelry on the market at present will definitely have corresponding markings, mainly PT999, PT990, PT950 and so on. And 18K white gold jewelry will be marked with 18K, G750, AU750 and other related marks.

White gold refers to platinum, so there is no difference between white gold and platinum.

There are 3 differences between platinum (white gold) and **

1. The chemical symbols of the two are different:

1. The chemical symbol of platinum (platinum): pt.

2. The chemical symbol of **: au.

Second, the color of the two is different:

1. The color of platinum (white gold): white.

2. Color: yellow, golden yellow, bright yellow.

3. The physical properties of the two are different:

1. Physical properties of platinum (white gold): pure platinum is a silvery-white metal with luster and malleability. It is the highest malleability of all pure metals, outperforming gold, silver, and copper, but its malleability is lower than gold.

Platinum metal is extremely corrosion-resistant, very stable at high temperatures, and has very stable electrical properties.

It does not oxidize at any temperature, but can be attacked by various halogens, cyanide, sulfur and caustic. Platinum is insoluble in hydrochloric acid and nitric acid, but it dissolves in hot aqua regia to form chloroplatinic acid.

2. Physical properties: Ductility is unusually strong, 1 ounce of gold can be drawn into 50 miles long, and its ductility makes it easy to cast, which is a good choice for making jewelry. Gold is the most tensile of all metals.

It has high malleability and can create extremely thin gold sheets that are easy to roll. 1 ounce of gold can be hammered as thin as 1 millionth thick and 100 square meters large. In ancient times, it was hammered into thin sheets to decorate temples and palaces.

These can show the extremely strong flexibility and malleability.

There is no difference between white gold and platinum. White gold is not a general term for all white gold metals, only platinum can be called white gold. The platinum and white gold in our cognition are the same metal, both of which are a natural white ***.

The properties of platinum are very stable, compared with the general ***, its stability is stronger, and it can be stored for a longer time. On the other hand, the amount of platinum mined is very small, often in short supply, and the amount of platinum is also very small, and it is relatively high.

White gold is often confused with white karat gold. However, white K gold is white gold in English, and the main ingredient is **, which is easy to fade due to the white color after adding other metals. Platinum (white gold) is naturally pure white and never fades.
