Rhodium is a very common plating for inexpensive jewelry, because it is extremely shiny and tarnish resistant. It's actually a very expensive metal, but you only need a microscopically thin layer to make something look beautiful, so it can be used for even very inexpensive items.

Rhodium Rhodium plated Ring with Tanzanite
3D3DRhodium plated Ring with Tanzanite.
Ed got this from eBay. Maybe some day he'll get a solid rhodium ring, but he probably won't donate it to my table.

A very small sample indeed, but since it's from David Franco, it is of course of the highest purity.

Rhodium Sample from the RGB Set
3D3DSample from the RGB Set.
The Red Green and Blue company in England sells a very nice element collection in several versions. Max Whitby, the director of the company, very kindly donated a complete set to the periodic table table.

To learn more about the set you can visit my page about element collecting for a general description or the company's website which includes many photographs and pricing details. I have two photographs of each sample from the set: One taken by me and one from the company. You can see photographs of all the samples displayed in a periodic table format: my pictures or their pictures. Or you can see both side-by-side with bigger pictures in numerical order.

The picture on the left was taken by me. Here is the company's version (there is some variation between sets, so the pictures sometimes show different variations of the samples):

Rhodium Sample from the Everest Set
Sample from the Everest Set.
Up until the early 1990's a company in Russia sold a periodic table collection with element samples. At some point their American distributor sold off the remaining stock to a man who is now selling them on eBay. The samples (except gases) weigh about 0.25 grams each, and the whole set comes in a very nice wooden box with a printed periodic table in the lid.

To learn more about the set you can visit my page about element collecting for a general description and information about how to buy one, or you can see photographs of all the samples from the set displayed on my website in a periodic table layout or with bigger pictures in numerical order.

Rhodium Museum-grade sample
3DMuseum-grade sample.
In early 2004 Max Whitby and I started selling individual element samples identical or similar to the samples we use in the museum displays we build. These are top-quality samples presented in attractive forms appropriate to the particular element. They are for sale from Max's website and also on eBay where you will find an ever-changing selection of samples (click the link to see the current listings).
This bottle contains about 50 grams of arc-melted buttons made in Max's reduced-pressure argon-arc furnace.

Rhodium Reed switches
3D3DReed switches.
These reed switches have rhodium-plated electrical contacts. I don't know why rhodium and not gold, a more common contact material. Reed switches work by opening or closing when a magnet is moved close to the sealed glass tube. These are normally closed switches.

Rhodium Questionable medallion
3D3DQuestionable medallion.
This commemorative medallion was advertised as being made of an alloy of 1/3 rhodium and 2/3 nickel. Very unlikely, but I haven't had it tested yet, so I'm not going to make a definitive statement yet.

Rhodium Rhodium-plated Sacagawea coin
3D3DRhodium-plated Sacagawea coin.
What a peculiar thing: Just for fun, someone with a rhodium plater decided to rhodium-plate an ordinarily gold-colored Sacagawea dollar coin and sell it on eBay. Curiously, I decided to buy it, for 50% over face value!

Rhodium Photo Card Deck of the Elements
3D3DPhoto Card Deck of the Elements.
In late 2006 I published a photo periodic table and it's been selling well enough to encourage me to make new products. This one is a particularly neat one: A complete card deck of the elements with one big five-inch (12.7cm) square card for every element. If you like this site and all the pictures on it, you'll love this card deck. And of course if you're wondering what pays for all the pictures and the internet bandwidth to let you look at them, the answer is people buying my posters and cards decks. Hint hint.
