Let's start with gold!
Solid gold:
Pure gold itself is very soft, and it is a jewelry material that is not easy to cause allergies. But because the texture is too soft, it is processed and fused with other metals to become a stronger "K gold". As a result, it is divided into 24 equal parts, the more equal parts contain the more pure gold content in this K gold jewelry!
Pros: Not easy to oxidize, not easy to cause allergies, high preserved value.
Cons: Expensive, low durability (Texture too soft).

K Gold(Karat Gold):
K gold is an "alloy" made of pure gold and other precious metals. The gold content of 14K accounts for 14/24, which is equal to 58.5% of pure gold, while the gold content of 18K accounts for 18/24, which is equal to 75% of pure gold.
It can also be divided into yellow K gold, white K gold, and rose K gold according to the composition and color!
Pros: It is not easy to oxidize, it is not easy to cause allergies, and its durability is higher than pure gold.
Cons: Expensive (lower than pure gold), the parts that are often rubbed are easy to fade. Rose K gold has a higher chance of discoloration when exposed to moisture or sweat because of its relatively high copper content
Platinum (PT950, PT900):
Platinum is not equal to white K gold! (White K gold is the alloy) Because platinum is not easy to mine; besides, its natural purity is high and relatively rare, so the price is the highest among precious metals! Platinum is also called the "King of Precious Metals!"
Pros: Maintain shiny, natural hypoallergenic metal, not easy to oxidize, rare.
Cons: The price is high (around twice as much as gold), and the production time is long.

925 Sterling Silver:
925 sterling silver, just as the name, contains 92.5% of pure silver (in order to make it stronger, it is processed and mixed with other metals), which has become the " international jewelry quality standard" of the world. However, why is silver jewelry so popular in the market nowadays? One of the reasons is that the silver ions in silver jewelry can effectively sterilize bacteria, prevent infection, or inflammation, and the human body is less likely to have allergic reactions to pure silver. Coupled with the luster of silver jewelry itself and its malleability, the silver jewelry market has always maintained a certain degree of heat! Compared with other precious metals, the price of silver jewelry is more approachable, and people who are prone to allergies, 925 sterling silver can also be a good quality choice!
Pros: affordable price, anti-allergic and anti-inflammatory ingredients (especially for those who have just pierced their ears), bright gloss, easy maintenance (just need to wipe it with a silver cloth after it turns black), high durability
Cons: It is easy to oxidize with sweat and sulfur then turn black, and the silver jewelry with high purity is easy to scratch.


316L Stainless steel:
316L medical steel is a high-alloy steel that can resist corrosion in the air. Because it will not repel or deform the human skin, it is often placed in the patient's body as a steel nail.
Pros: Not easy to deform, fade, oxidize, or cause skin allergies
Cons: high cost, sizing is hard.

Brass:
Brass is a base metal, and it is an alloy of copper and zinc. Because brass is easy to shape and low in price, it is often used to make jewelry. But why can't most of the brass accessories on the market be seen as the original color of brass? Because most of them use electroplating to coat the brass itself, brass oxidizes quickly (this is also why some people find green around their fingers after wearing a brass ring). In addition, brass is harmful to the human body, so if you have a sensitive constitution, try to avoid wearing brass jewelry, so as to prevent some toxic secondary metals in the jewelry from running into the body through the skin, causing rashes and allergies.
Pros: Inexpensive, retro style
Cons: Jewelry is easy to oxidize and fade, and the material is easy to cause skin allergies, itching etc.
