Can you plate white gold with platinum or silver? if so,
would it rub off as quick as rhodium?
thanks,

Gold is yellow metal in nature. we use nickel and
palladium in the alloys to turn it white with bleaching
effect. silver is whight in nature so it can give its colour
to gold and turn it a bit white. More the content of nickel,
palladium and silver, more the metal be white. but the
surface it not perfactly white and shiny. So rhodium is
deposited on it by electro plating process.
Rhodium is most brightest metal on this planet. But is
greyiesh in nature. it reflects the base metal colour so the
metal appears white and bright after rhodium platting.
You can get white, brown and yellow sports on your metal
surface if the rhodium process is not done carefully or the
metal surface is not cleaned properly before rhodium.
since rhodium is brightest metal, even a small scratches on
your piece will be clearly visible after rhodium. so the
piece should be nicely buffed before rhodium.
while plating, the person should take care of several things
like, the voltace and current at which the piece is dipped
in the rhodium bath, the time for which the piece is kept in
the bath, the bath temperature, the piece should be cleaned
properly, after cleaning its rinsed with DM water and then
before entering to the rhodium bath, its dipped in acid to
make the piece neutral (i.e. PH7). If this all instructions
are followed properly, you can get a perfect, clean, and
sportless rhodium plating on your metal.

I have recently read that the jewellery industry in the
UK has been aware of this problem and has recently graded
white gold on a 32 point system and then sub divided into 3
categories so the manufacturer or the retailer buying white
gold bullion or finished products will know what grade and
colour they are purchasing even if already plated . This
grading has been done through the gold council and assay
office .
Grade 1 - no need for plating
Grade 2 - option to plate
Grade 3 - requires plating

I think the main point that is rarely recognized in all of this
is: My grandmother and mother have white gold rings which have never
needed plating. Why is that? It angers me to hear "white gold is made
of yellow gold, which is yellow in color....bla bla bla... so deal
with it." Again, why do we all have relatives with white gold jewelry
that has never yellowed and never been plated? Anyway, yes, the same
thing happed to my wife and I. It is just disheartening to find out
that you now have to bring in your engagement ring and wedding bands
for plating every 6 months.... What? So how are we going to pass my
wifes ring on to our daughter? I guess with a maintenance plan for
say.... 100+ years.

It is indeed disheartening, Brian, and you are right about how big
a problem it is. I've learned a lot in the last few years --
Gold is yellow. There are no isotopes that are white; that is
scientific fact.
To make jewelry, jewelers mix gold with other metals because pure
24 karat gold is far too soft to be useable in jewelry. If the other
metals they mix it with are chiefly nickel or palladium, the
resulting mix will be "whitish". How white depends on which metals
they mix in, and in what proportion. A "whiteness scale" is mentioned
a few postings above.
Your relatives have rings where the right metal (probably
palladium) was mixed in, and in the right proportion, that the ring
came out satisfactorily white for them, and it stayed that
color over the decades.
Although your relatives' rings are indeed white, they are not the
brilliant shiny highly polished, diamond-like, chrome-plated-like
look of what you see in jewelry stores today. That is the look of
rhodium, not the look of white gold. Whether consumer-driven or
jeweler-driven, tastes changed to where people now expect white gold
jewelry to be that brilliant rhodium plated color. So it became
nearly universal to rhodium plate the jewelry, and you won't see much
unplated white gold jewelry; and if you do, you will find it quite
"dull" compared to the glittery rhodium plated stuff.
My assumption is that what happened is the jewelry industry
started saying to themselves "we're going to rhodium plate it anyway,
why spend the extra money for palladium in the mix", so they started
accepting white gold of lower and lower "whiteness" as the base,
worrying about it less and less. It seems that some jewelry stores in
the middle aisles of malls may even be rhodium plating regular yellow
gold.
Some people love the glistening rhodium plated look so much that
they accept frequent replating as the cost of getting it. I'm not one
of them. Like you, I believe heirloom jewelry should not be plated.
But I accept that that means it will be "white" but it will not be
dazzling because a mix of yellow gold and other metals, no matter how
well done, just can never be the brilliant dazzling color of rhodium.
Hope it helps.

I am in college and my boyfriend just proposed to me and the ring
already has the white gold peeling off and it looks horendous and we
have our engagement party coming up. can i get it replated and about
how much does this cost?

Peeling!? The plating is for some reason defective,
Nancy. It might eventually wear through, but it should never
peel.
Other threads in this forum indicate a replating cost of
about $30 to $50 at jewelry stores, although there are
plating shops which have expensive instrumentation and which
specialize in plating high quality jewelry, and they might
charge twice that.

Hello. I got engaged last December, and my ring is white
gold. I work at a bank and deal with change a lot so it got
pretty scratched up on the bottom, and I noticed that
yellowish tint. I did my research and understand fully the
reasoning for this. So I went ot have my ring re-plated. It
was very inexpensive (~$40), and looked like NEW! The
problem was that after about 2 months the same thing was
starting to happen. I haven't gotten it replated again
though. I was wondering if there was an amount of rhodium
plating I could request to be done at one time (like
thickness of it), to help keep it the way it is supposed to
look for longer. Anybody know??

My wedding set is of white gold. I take my set in
annually to have the rhodium placing done. From what I've
researched and from what I've been told, white gold loses
it's "white gold" color due to various reasons...chemical
reactions to skin, chemical reactions to lotions, soaps,
etc...also from salt water and just age. I fish and camp
often so my rings get dull quite fast. If you purchase your
rings with a warranty, the warranty coverage should cover
the rhodium plating on your ring. The rhodium plating also
help get rid fo scratches. I just picked up my set today,
takes about a week or so and about $35.00 per ring. They
come back looking as if your rings are spanking new. I
highly reccomend getting the process done annualy.

white gold sucks..after all the money ive paid for my rings I am
almost sick that it looks so dingy after a few weeks..I have been
told so many things- ohhh its having a reaction to your finger! Oh,
all metals tarnish..! Blah blah blah..its all a bunch of crap. Then,
the other day I went to get the rhodium plating done, and they told
me that i could not because it will damage my ring!! Meanwhile, I
have been sending it away to get the plating done for three
years..
Go for platinum..spend the money..or, just get yellow gold..save the
hassle..

I've been reading some of the comments. White gold does not exist.
Gold is yellow, no other color. It's Rhodium plated. You can go to
the jewelry store and get it rhodium plated every year, for about
$20-$40.
The yellowish of ring is the gold and nothing else.

Not quite true, Natalie. Because this issue is very confusing
spread across hundreds of postings, we've summarized it all for easy
reading as our FAQ on Rhodium
Plating and White Gold.

Hi Ted,
Ok, I read the FAQ, if I understood right, gold is yellow, to make it
white gold they add other metals to make it white....am I correct on
this? Now the rhodium plating is a metal just to make the surface of
the band brighter/blink blink! LOL
If correct, the ring is just high maintenance. Regardless it's still
gold and it isn't worth any less than the yellow gold ring.

Yes, that is my understanding, Nathalie.
I've been married 39 years and just bought the 3rd
setting for my wife's ring because two wore out over the
decades. I doubt we'll be around long enough to wear this
one out, and whoever we pass it on to won't have to worry
about replating because we went yellow this time :-)

Hi,
Just had a quick question. I had recently found out about
rhodium plating and just had it done yesterday for the 2nd
time in 3 mos. My wedding set is yellow gold and I love the
look of the white gold after the plating is complete. The
jeweler yesterday said that if I continue to have my rings
plated, they will become brittle and ruined over time and
have to be rebuilt. Is this a fact? It's free for me to have
it plated from the jeweler I bought it from. I realize now
from the prior posts that the jeweler is probably putting a
very thin layer of rhodium on and what doesn't help matters
is the increasing cost of gold and other metals. I don't
mind getting it done but if it's going to ruin my ring, I'll
stop. Is there any fact to this?

Hi, Elaine. The biggest problem, as mentioned in the FAQS, is that
the contrast between yellow gold and rhodium is so drastic that your
ring becomes unsatisfactory looking very quickly. While I haven't
heard of rings becoming brittle because of too frequent replating, I
suppose it's possible if you are doing it every couple of months.
The price of rhodium is presently off the charts (literally! see
www.kitco.com/scripts/hist_charts/yearly_graphs.cgi). It was $7000
per ounce in January and is $9,000 per ounce now. Although little is
needed, I don't think you will be able to afford replating every 2
months forever, not to mention the inconvenience. Please consider
letting your yellow gold ring be yellow.

WAS WONDERING, COULD I GET YELLOW GOLD AND DIAMOND EARRINGS
RHODIUM PLATED? I LOVE THE EARRINGS, BUT HAVE STARTED WEARING WHITE
METALS EXCLUSIVELY.

Hi, Judy. It's only a matter of how long the rhodium plating will
last before wearing off considering the strong contrast. It's not a
good idea for a ring, but for earrings that you wear only
occasionally, and that don't get friction like a ring, it will
probably be fine.
Regards,

Unfortunetly I could not read all the comments on this topic, I
just got too tired to read of the same problem over and over again.
But please read the following.
I am a Jeweller and I personally re-plate jewellery for a
living.
The truth is that plating Rhodium over white gold is a jewellery
making standard. Depending on the kind of alloys, the color may vary
on white gold. What consumers need to know is that Rhodium is realy a
PLATING and it DOES wear out. Depending on how often jewellery are
used and on the person, as well as on the quality of the plating and
solution used. Some jewellery are hollow and the jeweller doesn't
want to risk to contaminate a $450 solution, so he uses older
solution.
Consumers also need to understand that a piece of jewellery CANNOT
stay shiny forever. It's normal when the surface gets scratches over
time.
There is no way to keep jewellery shiny forever. They need to be
cleaned and polished regularly.
Now, if you really don't want you jewellery to discolor ask you
jeweller to make your jewellery using SUPER WHITE K19 WHITE GOLD.
This alloy does not require Rhodium plating and will stay white
forever. Furthuremore, it will REQUIRE polishing and cleaning
regularly.

We are a manufacturing jeweller located in South Africa.
We often manufacture wedding bands for couples. Typically, mostly
because the engagement ring is 18ct white gold, the lady's ring is
made in the same metal.
Gents are generally rougher with their hands and so we mostly
manufacture their rings in 9ct white gold which is more durable. The
lower gold content (37.5%) + the other white alloys combine to give a
whiter finish without the need for rhodium plating.
This is the main reason why gents bands do not tend to go yellow.

I've just read this thread with fascination. I have an 18ct white
gold wedding ring and engagement ring. I've been married 4 years. 10
months ago I took the wedding ring in to the jeweller to be
re-plated. This was the second time I had had it replated in the 3
years I had been wearing it (not the once every 5 they had originally
advocated). Since I got it back last November, I literally only ever
wear it to go to the office, I've been so careful with it, never wear
it in bed, in the shower, to do DIY or gardening but not because of
the 'turning yellow' problem cited here, but because despite the fact
I hardly wear it, it is getting dinged and dented like you have never
seen. Some of the sratches are so big you can fit a small fingernail
down them. My engagement ring which I wear at the same time does not
have this type of problem at all. I took it back to the jeweller at
the weekend and he agreed that it looked more like a wedding ring
that had been worn for 20 years, not 4 and was astonished when I
related how careful I am with it. He started in about how I might
have some sort of skin allergy to white gold but I find it hard to
understand how a skin allergy, if it is such a thing, might be
gouging scratches and dents in my wedding ring. It has now been sent
back to the manufacturers for some kind of 'deep' re-rhodium plating
which is going to take up to 4 weeks with a long explaination of what
the problem is, but I'm not connvinced that this is going to solve
the problem. A wedding ring should surely last for life but it this
carries on we'll be buying a new one within a few years. Does anyone
have any experience of this type of problem?
