Is 18k gold better or platinum, the difference between 18k gold and platinum

It should be the difference between platinum and 18k white gold:

1. White K gold is impure, it is a white alloy smelted with palladium or nickel, silver, copper, zinc and other metals, and its main component is still. Platinum (PT) is a naturally occurring white***. The state stipulates that only jewelry with a platinum content of 85% and above can be called platinum jewelry and must bear the PT mark.

The difference between K white gold and ** is also reflected in the rarity of the raw material, only 88 tons of platinum are made into jewelry every year, while ** has 2,700 tons.

3. The chemical properties of platinum are more stable than **, and ** is also more expensive than **, and it is used to make high-end jewelry. There are generally two kinds of platinum jewelry on the market, pt950 and pt900, that is, platinum containing 950 and 900 respectively. 18K white gold is a mixture of gold (AU) and a small amount of other precious metal elements, and the 18K white gold seen on the market is 75% pure.

It is made by mixing 75% ** plus 25% silver, nickel, copper and other metals, that is, white K gold, marked as 18K white gold, AUG and so on. Because of the different elements added, K gold has three colors: red, white, and yellow.

4. In terms of durability, the density and weight of platinum 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. 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.

It depends on whether you want to set diamonds or not.

If it's just plain gold, it shouldn't matter, but platinum won't fade, 18k will be a little yellow after a long time, but it can be refurbished, that is, platinum ** will be relatively high, if it is inlaid with diamonds, it is best to be 18k gold, platinum gold content is high and soft, if it is used to inlay diamonds, I am afraid that it will be deformed if it hits it, and 18k gold is hard, and the diamonds will be firmer, although it will change color after wearing it for a long time, but it will be better for the diamond to be stable on it or 18k gold.

Platinum and karat gold each have their own advantages and disadvantages. The advantage of platinum is that it does not change color, and the disadvantage is that it is easy to deform. The advantages of K gold are high hardness, and the disadvantages are that it may change color. Comprehensive recommendation of 18k gold, discoloration is off, and the diamond is big.

The differences between 18k gold and platinum are as follows:1. The color is different. The first difference between platinum and 18k gold is the difference in color, platinum is an eternal white metallic luster, even if it is dull, it can be restored after cleaning only because of dust; There are three colors of 18k gold, white, yellow, and rose gold, which are rich in color and selective, so they are very popular, but white and rose gold will turn a little yellow after wearing them for a long time.

2. The purity is different. Purity is the second point of the difference between platinum and 18k gold, the purity of platinum is relatively high, and now the common platinum is pt950, which contains 95% platinum and is not easy to allergies, while 18k gold is an alloy containing 75% ** and 25% other ***.

3. Scarcity is different. Platinum is more precious than **, ** contains about 25 times more than platinum on earth, while 18k gold only contains 75%, so the difference between platinum and 18k gold is that platinum is more scarce than 18k gold.

The difference between 18k gold and platinum is mainly reflected in the following four aspects:

1.Composition: 18k gold is an alloy of ** and other metals, usually ** content reaches more than 75%, while platinum content is more than 95%.

2.Color: 18k gold comes in a variety of colors, including white, yellow, rose, etc., while platinum comes in pure white.

3.Platinum is usually higher than 18k gold, due to its rarity and difficulty in processing.

4.Uses: Both 18k gold and platinum can be used to make jewelry, but 18k gold is more common because it is harder and more suitable for making intricate designs.

In general, 18k gold and platinum are both precious metals, but there are obvious differences in composition, color, ** and use. The choice of jewelry material depends on personal preferences and budget.
