925 Sterling Silver, Rhodium-plated
Rhodium is the most expensive metal on the planet, even more so than gold or platinum, and is extremely rare. It is hypoallergenic (nickel-free), extremely lustrous, withstands corrosion, and is highly durable. All these qualities make rhodium perfect for jewelry, but due to the hardness and brittleness of the metal, and the exorbitant cost, it's not being used in its pure form to make jewelry. The only way rhodium is used its for jewelry plating.
925 Sterling Silver is an alloy made of 92.5% pure Silver and 7.5% Copper.
One of the characteristics of silver is that it tarnishes easily, developing a dark patina over time. As a result, silver must polished frequently to retain its shiny luster. Rhodium, on the other hand is highly tarnish resistant and does not corrodes, stains or change color. By plating sterling silver with rhodium, tarnishing can be avoided, and the piece of jewelry remains white and lustrous much longer.
We plate our silver jewelry in rhodium, which gives it extra shine and durability.
