Platinum (Pt for short) is a kind of natural white precious metal, which has the eternal noble characteristics of natural pure white, never fading, no grinding and no damage. It changes with time and lasts forever, and its natural pure white color is moist and shiny, which is a symbol of purity, rarity and eternity. When buying platinum jewelry, please be sure to look for the "platinum or Pt logo".
Platinum, the main component is 75% gold, and the surface is white after adding other metals. Therefore, white gold is an alloy, which will fade or yellow when worn for a long time. Please remember that everything marked "K/750/AU/H" is a mixture of gold and other metals, and its white color is added, so it cannot be kept forever.
"K gold" refers to the purity of gold and refers to the alloy in which gold and other metals are melted together. K gold is rich in color, including white gold, yellow gold, rose gold and black gold. The gold content of 1K is 18×, which means that the gold content of "18K platinum" jewelry is 75%.
In fact, from the above two concepts, we can understand that, first of all, they are two different substances, one refers to gold of gold; One is platinum, which is what we often say.
So the difference between K gold and platinum is very obvious, because they don't refer to the same substance at all. Moreover, the price of gold is lower than that of platinum, and the price of K gold is generally lower than that of gold. Therefore, the price of K gold is not as expensive as platinum.
At the same time, there is a kind of white gold in K-gold, which may be similar to platinum in appearance, but in jewelry, white gold cannot be marked with Pt (platinum), and gold and its purity can only be marked according to its purity. For example, 18k platinum can only be stamped with "18k" and "G750".
