Rhodium Plating; Like Coloring Your Hair, Only for Jewelry!

Rhodium plating is a bit like visiting your favorite hair salon.  Getting bored? Add Purple. In the same way you can lay purple over brunette, rhodium plating can cover faded looking white gold and dramatically transform the look of your jewelry.

Like adding purple to your hair to create drama, which does come out as you wash it. Rhodium plating is a topical treatment, and doesn’t go down into the gold.

What is Rhodium?

Pure Rhodium. This Makes for an Excellent Coating Material.

Rhodium is a rare, naturally occurring member of the platinum group of metals.  It’s extremely hard. It’s silvery in color and highly reflective.

It’s inert against corrosion and doesn’t react with most chemicals.  These properties make rhodium especially good for electro-plating.

Rhodium Plating: What is It?

Jewelry plating—including rhodium plating—is essentially covering one metal surface with a very thin layer of another.  This is done using electrolysis. It’s called electro-plating.

In this process the item to be plated is dipped in a liquid solution containing the plating metal.  When an electric current is added to the mix, the tiny suspended particles of plating metal bond to the surface of the immersed piece of jewelry.

Rhodium Plating: Why I Love It

Rhodium Plating Makes it Look White Gold Like Magic!

Rhodium is often used to plate white gold jewelry.  Because of the very bright and shiny nature of rhodium, it gives white gold a nice “pop.”

Rhodiumed rings look whiter and brighter.  Like washing with Tide!  More often than not, white gold pieces of jewelry you see in jewelry stores have been rhodium plated.  It’s the final step in lots of white gold jewelry.  Again, it gives pieces the “pop” and “zing” that we like and come to expect.

Likewise, silver jewelry is frequently rhodium plated.  Not only does this add shine and sparkle to the piece, but it helps in resisting tarnishing.

As you can imagine, rhodium plating is a relatively inexpensive way to turn a yellow gold piece of jewelry into a white gold piece of jewelry.  It can be as easy as getting your hair done at the salon!

How Does Rhodium’s Hardness Compare to Other Jewelry Metals?

MOHs and Vickers Hardness Scales

Getting technical here. Platinum is 4.3 on the MOHs scale of hardness. Rhodium is 5.5. The scale is not an even one, so the translation is that rhodium is ten times as harder than platinum.

Moving over to the Vickers Scale, a hardness scale for materials, is also useful for comparing rhodium’s amazing hardness to various alloys of platinum used in jewelry. Pure platinum is a 40, 850 platinum with iridium is 160, (85% pure platinum and 15% iridium), 950 platinum with iridium is 80, platinum with cobalt is 135 and platinum with ruthenium is 130. Rhodium soars at 800.

That high number is why I like to use rhodium to plate over platinum jewelry to slow the effect of platinum dulling that occurs on daily wear rings.

To give equal time to white gold which I use frequently in wedding rings, 14kt white gold on the Vickers Scale is a 230.

Graciela’s Heart (A Heart-Warming Tale)

Yellow Gold Prongs Can Compete With the White Brightness of  White Diamonds

Graciela  had me do repairs on her current jewelry.  I was at her home delivering her pieces. She said, “it’s like having new jewelry, I love it.” I asked if she had any non-broken jewelry that she wasn’t wearing. “Oh yes!” she said immediately. A few minutes later she came back with a diamond necklace. She said it hadn’t seen the light of day for a while. I could tell by just the look in her eyes and the way she looked at it, that it had a great deal of sentimental value.

Sure enough, she told me she had received the diamond pendant from her husband.  The center larger was surrounded by many smaller diamonds.  She really wanted to wear the ring and I could tell she loved both of them a lot—her husband and the ring.

I looked closely at the pendant, it was almost pretty…but not quite!  The problem with the piece was that there was too much yellow gold showing between the older diamonds.  Graciela regularly wore yellow gold, so her husband had taken inherited and very old diamonds and had the pendant made in yellow gold. “I just don’t reach for it. It looks, not great.”

I explained how yellow gold prongs can make white diamonds look smaller, by covering the diamonds. I also pointed out that diamonds can look a bit off color with the yellow gold next to it. The older diamonds in the pendant were not that white to begin with. I thought that if we made the prongs look white that it might very well improve the look of the diamonds. Often when diamonds are held with a white metal it enhances their color, making them look whiter. If the prongs blend in and didn’t compete with the diamonds, the diamonds look bigger and better. At this point I told her that we could ‘white’ her pendant with rhodium plating.

White Prongs Show Off Diamonds Without Competing With Them

A week later I sat next to Graciela on her living room couch.  She was now excited and hopeful and animated all rolled up into one.  I handed her the bag with her name on it.  She eagerly reached inside and pulled out the little package.  As she unwrapped the purple paper, revealing her pendant, her smile couldn’t have been wider.

“I love it!” she said. She tilted it this way and that. “The diamonds look whiter and the whole piece just looks better. A lot better.”

“That’s the magic of rhodium,” I said.

What about You?

White Gold Can Get Dowdy Looking. Rhodium Brightens it Beautifully

Do you have jewelry like Graciela’s?  Jewelry that hasn’t seen daylight for a while?  Jewelry that looks dated?  Out of style?  Not quite right?  Dull, scratched, and a slightly faded?

A little rhodium plating is all it might take to transform your old jewelry into something new and exciting.  A touch of rhodium is all it might take for you to love your jewelry all over again!

Calla,
Love this article! Very informative and it’s made me think about jewelry I have that might need some ‘updating’!
Thanks for posting this!

I just met a woman who was showing off her heirloom engagement ring. When I commented that it looked like it was in great condition for an heirloom, she explained to me that she had just had it Rhodium plated. I had no idea what she was talking about, but now I do! Thanks for an informative and interesting blog post.

This is a great article!! Super informative and easy to understand for us “non-jewlery” people! I’m so happy we went with rhodium plating for my engagement ring… you’re right in that it’s really shiny and bright! Thanks again for all your help!

Calla Gold,
Can you tell me about how much this rhodium plating costs? And do the stones have to be removed before the ring is dipped? I have a yellow gold ring with a lot of baguettes that I would love to change to a white gold color and I have no idea if it’s feasible b/c of the number of baguettes and stones.
I doubt I can afford for it to be completely taken apart and reset. And how often must a ring be redipped?
Does the rhodium wear off quickly?

Thank you for your response. I am not near the Santa Barbara area, but I really appreciate the information. I spoke to a local jeweler yesterday about having my ring plated and we are considering just plating the setting and leaving the band yellow. I would love to have it ALL plated, though, and if the cost is less than $75 to do it yearly I think I might do the whole thing anyway. Thanks again for your personal reply 🙂

My ring is being done this week, I can’t wait to see it. We settled on just doing the setting for now, since I have a very wide setting and you can’t really see my band except from the underneath, and the band’s plating will wear faster we just decided to forgo it. And if the 2-tone look just looks “off” then I’ll go ahead and have the band done as well later. Thank you for all your information.

Hello Calla Gold Jewelry I have a question for you. Can Rhodium plating be done on metals other than silver and gold?

I have a large gold plated ring over silver
that I would like replated as the gold is
wearing off. I do not want a change in the
design just replated. Can I mail it to you?
and approximately how much? I will call you
Monday

I sell fashion jewelry but I LOVE fine jewelry too. Do you do black rhodium plating as well? I have an older yellow gold ring with some diamonds channel set that I never wear anymore and have thought it would be so new and trendy looking in black as a right hand ring.
