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 alloying components,
It is silver from which silver reacts easily.

Rare silver is excellent at preventing sudden discoloration due to sweat.
In addition, rare silver may be discolored under circumstances that change silver.
Please note that there is.

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