Posted on June 22nd, 2016 by JoeG

There are several different types of metals in the world. Often times our team of experts at Chicago Gold Gallery are asked what the most expensive types of metals are. In this post we will discuss 5 of the most expensive metals in the world and where they come from.
Platinum

 

Platinum

Platinum is one of the rarest types of metals in the world. It is about 30 times more rare than gold. Platinum is used in jewelry, applications, weaponry, dentistry, aeronautics, and more. Platinum is found in Russia, South Africa, and Canada.

 

Gold

Gold is one of the most common and recognized precious metals in the world. Gold is said to be the most ductile and malleable metal of all precious metals. Gold is the perfect metal for commercial applications and jewelry. Also, gold can be used as a protective coating in many different artificial satellites. Gold is found in South Africa, the United States, China, and Australia.

 

Palladium

Palladium jewelry is often created with white gold alloys. The United States, Canada, and South Africa is where Palladium can be found.

 

 

Iridium

Other uses for Iridium are iridium crucibles in the manufacturing of sapphire crystals, a process requiring temperatures of around 2,000 degrees celsius. For many years prior, iridium had already been used to produce single crystals used in LEDs.

It is a member to the platinum family and is a silvery, hard and durable metal. Silver is plated with rhodium to make it resistant to tarnish. Rhodium is mined in Russia and South Africa.

Customer Testimonial

Had a Great Experience

"I recently worked with Chicago Gold Gallery to design an engagement ring. From picking out the stone to designing the setting, it was a wonderful experience to say the least. Thank you so much for your help!"

Can't say enough about this place.

Recently took my family of 4 for a week to Chicago for a family vacation. We were on a limited budget but being lifelong Cub fans I thought it would be a great treat for my kids ages 7 and 10 to go to a game that we hadn't planned for...

Love this place!

Chrissy & Joe are all super friendly and easy to work with. I trust them and they will do whatever they can to help you including giving you advice on what you have or what you should look for. I won't ever go anywhere else and I've recommended it to several friends.

I would do business with them again

I had a diamond ring that I wanted to sell and they gave me top dollar for it. They were so nice and I would do business with them again.

Don't Hesitate to call...

I find that Joe at Chicago Gold Gallery consistently offers and pays more for my coins than coin dealers in Chicagoland. He's very nice and easy to deal with. Don't hesitate to call him and preferably visit him.
