Forget almost all white gold if you have a metal allergy. When clients ask me about hypoallergenic metals for engagement rings, that is the first thing I tell them. Nickel is the most common skin irritant in jewelry, and most 14k and 18k white gold on the market uses nickel for whiteness and hardness. A rhodium plate hides it for six to eighteen months, then the rash shows up on the underside of the band. The metals I actually recommend for a sensitive hand are platinum, palladium, and 18k yellow gold, in that order.
The best hypoallergenic metals for engagement rings
If I had to rank them for a daily-wear ring, platinum comes first. Then 18k palladium white gold. Then 18k yellow gold. That ranking assumes you want a white metal. If you are open to yellow, 18k yellow gold is the simplest answer and often the least expensive hypoallergenic option.
Platinum, specifically 950Pt/Ru
For a client with a genuine nickel allergy, platinum is the safest thing we can put on a hand. It is 95% pure platinum by weight. The remaining 5% matters. I use the ruthenium alloy, 950Pt/Ru, because it is harder for prongs than the cobalt alloy and it casts cleanly. Cobalt is not the allergy culprit nickel is, but some people do react to cobalt, and ruthenium is essentially inert. If you are going to pay for platinum, ask for the ruthenium alloy by name.
Platinum has a reputation for being the premium choice, and for allergies it earns it. It deforms before it abrades, which means a platinum prong will bend rather than wear away. The patina it develops over twenty years is something I have come to like. The downside is weight and cost. A simple platinum solitaire setting in our studio starts around $1,450 and goes up with pave or a cathedral.
Last spring a client named Emily came in with a red rash exactly where her 14k white gold engagement ring sat. She had been told it was probably soap. It was nickel. We rebuilt the ring in 950Pt/Ru with the same 0.92 carat oval diamond she already owned. The snag was her budget did not include a platinum setting, so we dropped the hidden halo she wanted and kept the center stone in a plain six-prong. No rash since. I still have the photo of her hand on my phone.
Palladium white gold, the less expensive route
If platinum does not fit the budget, the second choice is 18k palladium white gold. Not nickel white gold. Palladium white gold is 75% gold alloyed with palladium and sometimes a little silver and copper. Palladium is a platinum-group metal. It does not cause the nickel reaction. The trade-off is that palladium white gold has a slightly warmer gray color than nickel white gold, so it still gets rhodium plated for that bright white finish. The plating will wear, but what is underneath is not going to irritate most people, and that is the point most allergies are actually reactions to the nickel hiding below the rhodium.
There is also 950 palladium, which is 95% pure palladium and hypoallergenic. It is lighter and grayer than platinum, and I have worked with it enough to know it casts fine, but most jewelers will steer you to 18k palladium white gold because it is easier to repair and replate. A 2.2mm 18k palladium white gold solitaire setting runs about $900 to $1,250 before stones, which is usually less than platinum but more than standard nickel white gold.
18k yellow gold
Yellow gold does not get enough credit in the allergy conversation. 18k yellow is 75% gold, with copper and silver making up the rest. No nickel. It is warm, rich, and ages better than 14k in my opinion. The patina after a decade is not dullness; it is depth. For a client who wants a non-white metal and has sensitive skin, this is the one I push, and the patina after a decade is not dullness but depth.
The exception is if you have a documented copper allergy, which is rare. In that case we go back to platinum or palladium. But for the vast majority of people who say they are allergic to gold, what they are really allergic to is the nickel in white gold. Yellow gold becomes the easy fix they overlooked because they wanted a white metal.
Metals I would not set an engagement ring in
- Titanium and niobium. Hypoallergenic, yes. But they cannot be sized once made, and prong setting is limited. Fine for a plain band, bad for a ring meant to hold a stone and be resized over fifty years.
- Tungsten. Same sizing problem. Tungsten cannot be resized, only replaced. I will sell a tungsten men's band if someone insists, but not an engagement ring.
- Nickel white gold. Just avoid it if you react. The rhodium plate is not a permanent shield.
That list is short because the real decision is usually between platinum and palladium white gold, with yellow gold as the quiet third option.
What to ask your jeweler
Do not ask if a ring is hypoallergenic. That word gets thrown around by every counter clerk who does not actually know the alloy. Ask three things instead: what is the exact alloy, does it contain nickel, and what is under the rhodium plating. If the answer is vague, leave. A real jeweler will say 950 platinum with ruthenium or 18k palladium white gold without blinking.
One last thing. Rhodium plating is itself hypoallergenic. The problem is never the rhodium. It is what happens when the rhodium wears through at the underside of the band around month eight or nine. You will think the ring is fine because the top still looks white, and the rash will start where the plating has gone. That is why the underlying alloy matters more than the shine on day one. If your jeweler cannot tell you what is underneath, do not buy the ring. Walk out.
