The unique meaning and month of the birthstone
Caille put together the cases of the East and the West.

It is light water color.

What is Rare Silver?

Rare Silver is for customers who are concerned about the sudden discoloration of silver due to sweat.
This is the product you are looking for.

Rare silver has the same content as sterling silver (Jeong Eun) 92.5%.
By alloying a small amount of platinum with the remaining alloy components,
It is silver from which silver reacts easily.

Rare silver is excellent at preventing sudden discoloration due to sweat.
In addition, under conditions that change silver, rare silver may also change color.
Please note that there is.

✽ Due to the high production cost, there are products that cannot be manufactured with rare silver depending on the product specifications, and there may be some stains from the alloying process.
