What is the difference between K10 and K18? A jewelry designer from a lab-grown diamond specialty store explains this question !
Do you know the difference between K10 and K18 ? "What's the difference between K10 (10 gold) and K18 (18 gold)?" This is a question we often get asked by customers and friends.
This is a question that is often asked by customers, so I would like to explain it when you are unsure of which jewelry to choose or which is better .
[What is the difference between K10 and K18?]
What is the difference between K10 and K18?
Perhaps the purity of gold is different...? K10 is cheap and K18 is more expensive...? We will introduce you to the details of this material that many people do not know about.
⚫️Why is gold written as K and the number?
■ " Karat " is a unit of measurement for the purity of gold.
■ " Carat " is a unit of measurement for the weight of a jewel.
We often hear these things every day. Carat is a unit of weight for jewels, so the gold purity we will talk about now is I would like to talk about this using the unit Karat .
The "K" at the beginning of K10 and K18 stands for karat, a unit that indicates the purity of gold contained in gold products as a percentage.
The purity is expressed as a number called "finition," and the amount of gold contained (content) is expressed as a percentage of gold contained in jewelry, with K24 being 100% (pure gold).
K18 (18 karat gold) is 75% gold, and K10 (10 karat gold) is 42% gold. K18 contains 75% gold, and K10 contains 42% gold, so they are 18 karat gold and 10 karat gold , respectively.
Few people may realize that K10 contains less than half gold.
[About the characteristics of gold]
Next, let's talk about the properties of gold.
⚫️It is insoluble in acid and does not oxidize easily → Less discoloration or corrosion over time
⚫️Low melting point and excellent ductility → Easy to process
This characteristic of gold makes it an ideal material for jewelry. As such, it is extremely unlikely to fade or corrode over time, so its "unchanging shine" is a major characteristic and attraction of gold.
However, gold itself is very soft and easily scratched and deformed, so it is alloyed with alloying metals such as palladium, silver and copper to achieve the optimum hardness.
[What is an alloy? Can I change the color of my jewelry?]
Gold is a standard in jewelry, but have you ever wondered why there are variations in color even for the same K10 or K18, or why the yellowness of the same yellow gold varies depending on the brand?
The same gold
"Pink Gold (PG)""Yellow Gold (YG)"
"White Gold (WG)"
Broadly speaking, they can be divided into these three types , but the gold content remains the same while the color is changed by the amount of alloy added.
The alloys contain metals such as silver, copper, and palladium.
There are no clearly defined regulations or rules regarding this, so the percentages of silver, copper, palladium, etc. may vary depending on the company, manufacturer, brand, and whether it is domestic or international, and other metals may also be included.
Therefore, even if it is the same yellow gold, there are slight differences in color. *Pink gold has a pink color because the ratio of the alloy metal, the core, is higher than that of silver.
How can I check the quality of my jewelry?
To check the purity and fineness of the gold in the jewelry you own, you can check the hallmark.
Engravings such as K10, K10PG, K10WG, K18, K18PG, and K18WG are engraved on the inside of rings, earring posts, and chain clasps, so take a look at your own jewelry.
Additionally, overseas products have an "Ato K" stamp, which is mainly seen on gold products made overseas, and has a K at the end, such as "18K."
Not all products are like this, but some have a low gold content or are of poor quality, so you should be careful when purchasing.
【summary】
What did you think? To sum up what we have introduced about gold this time,
⚫️The percentage of gold in jewelry is expressed in 24 parts, with K24 being 100% (pure gold), K18 (18 karat gold) being 75% of the total, and K10 (10 karat gold) being 42% of the total.
⚫️Gold is a very suitable material for jewelry because it does not tarnish or corrode over time and is easy to process.
⚫️ "Pink gold (PG)", "yellow gold (YG)" and "white gold (WG)" have the same gold content, but the color is changed by mixing alloys containing metals such as silver, copper and palladium.
⚫️To check the purity and fineness of gold, check the engravings engraved on the inside of the ring, earring posts, chain clasps, etc.
