Red gold: Omega constellation coaxial 27 mm female watch
Orientals like gold very much, but soft gold is easily deformed and easily worn. Therefore, ancient people began to try to add a small amount of other precious metals to pure gold to increase the hardness of gold. Silver, copper, zinc, etc. are metals that are now commonly added to gold to increase strength and toughness. Gold is added to other metals, which is the most commonly used K gold on watches and jewelry. The determination of the content of K gold in the English is called "Karat" in English, and can also be referred to as "K" in English. Therefore, the gold is also known as "K gold."
The most acceptable of the K gold is 18K gold. 18K gold jewelry is usually engraved with the mark of "18K" or "750". This is because in 18K gold, the gold content is 75%. To calculate the amount of gold in each K gold, you can divide the number before K by 24 to get the amount of gold in the synthetic metal. For 18K gold, 18÷24=0.75, that is, the gold content in 18K gold is 75%.

Nowadays, K gold has a lot of colors. When gold is fused with other metals, as long as different kinds of metals are added, K gold of different colors is formed. For example, the most common red color now is copper, white and silver or nickel or palladium, and green is added with pure silver.
The red series of K gold jewellery is mainly made of gold and copper. In 25% of the gold, 25% of the electrolytic pure copper is red gold. The 18K gold color formed at this ratio is the reddish color. When you add silver, the color will become lighter. The more silver you add, the lighter the red color will be. When 18K gold, the silver content increases to 10%, and when the copper retreats to about 15%, the color will be more powdery, and it will become rose gold. So, in fact, red gold should look redder than rose gold.
