What Is Rhodium?
Rhodium is a precious metal similar to gold, silver, or platinum but only much more expensive! In fact, it is the most expensive of all the precious metals.

Since it is such a precious metal why have we seldom heard of a solid rhodium jewelry?
Why Don't We Make Solid Rhodium Jewelry?
The reason is simple; the price of rhodium is very volatile and has huge ups and downs. To illustrate how extreme the price can become, rhodium can sometimes skyrocket to ten times the price of gold to $10,025 just before the 2008 financial crisis.
Other times, rhodium prices skydives down to the price of gold or platinum to around $1000 per ounce in early year 2017.

Rhodium is cost almost twice the price of Gold today.
Because of the high vitality phenomenal, rhodium is not the most stable of investments. Gold is still kept as the "Gold standard" for precious metals due to its low volatility in price in compare to other precious metals.
Another reason why rhodium is usually used in plating but not as a solid rhodium jewelry is because, when pure, it is brittle and not very malleable thus it is very challenging to be crafted into fine jewelry.
Why Is Rhodium Such an Amazing Precious Metal?
Rhodium is commonly used to hide imperfections and bring forth a greater brilliance to silver or white gold pieces. Being both resistance to corrosion and harder than both silver and gold, rhodium plated jewelry will have an excellent protective coat that shields jewelry from scratches and retains its shine.
While rhodium is both too expensive and too brittle to make jewelry out of, it is always the precious metal of choice as a plating material for other fine jewelry.

Well for every hero there is always a weakness. There are some cases when rhodium plating just doesn’t work.
As rhodium is extremely expensive only a very thin layer of rhodium is used in plating procedures. Over the years, this layer of rhodium will eventually come off, making re-plating a necessity. When it comes to pieces like rings or necklaces which come in close contact with the skin, the rubbing causes the plating to come off more quickly. This leads to a need for a thicker layer of plating, which, in turn, changes the color of the jewelry piece.
As Rhodium itself it brilliant silvery-white, it is not suitable for yellow gold which is yellow in nature or vintage silver.
While rhodium plating is the star of the platinum family and works great to further brings the shine to diamonds and cubic zirconia, different lines of products require different finishes.
