Ring material: Gold
Chic, gorgeous, simple. Gold is a material that can be enjoyed in a variety of ways depending on how you wear it.
Even within the K18 that is often used for rings, there are different types based on the amount of alloy (a mixture of multiple metals) contained.
K18 is 75% pure gold with 25% alloy.
The role of alloy is to increase the hardness of the ring, make it stronger, give it color, and make it easier to work with. Yellow gold rings are mainly composed of silver and copper, and if the proportion of silver is higher, the ring will be green, and if the proportion of copper is higher, the ring will be closer to red.
Six-fourths (Shibrok)
An alloy of 40% silver and 60% copper is called Shibunroku. It is characterized by a slightly reddish color due to the high copper content. This alloy was mainstream until the 1960s.
It has a classic impression, and some of you may have had your grandmother's wedding ring in this color.
I remember my grandmother also having a gold wedding ring that looked darker than the gold rings we often see these days.
I fondly recalled that it was probably six-fourths of a second.
Five-five (Go-go)
Half silver and half copper.
Since the 1970s, there has been a trend to reduce redness, and this 55% red color has become more common.
Sixty-four (Rokuyon)
Also known as Gyakushibu, this is a 6:4 ratio of silver and copper. This is the 6:4 ratio used at KARAFURU.
It has a low copper content and a strong yellow color, and is the mainstream gold ring today.
It has a delicate, radiant beauty.
You may be wondering, aren't all gold rings the same color?
As mentioned above, the color changes slightly depending on the alloy, which is what makes it interesting.
If you are looking to create a ring to wear together with an antique ring (a six-quarter ring) inherited from a family member or loved one, you may want to be careful as the color will differ from the mainstream today.

It's a small ring, but it's fascinating how a small proportion of metal can change the color and atmosphere.
