The moissanite stone will not turn your ears green. It is silicon carbide and contains no copper. When any earring leaves a green mark, the cause is copper in the metal reacting with sweat and skin oils. Mariqe studs are 925 sterling silver with platinum or 18k gold plating, so the same note applies as for any silver or plated earring: it can happen, it is cosmetic, and it washes off.
The stone: nothing in it can stain skin
Moissanite is a lab grown form of silicon carbide. It is chemically stable and does not corrode, so there is nothing in the gem that can transfer to your skin. The stone sits in a six-prong setting, and the part that touches your ear is the metal post, not the gem. If you want the detail on how the stone behaves around water, see can you wear moissanite jewellery in the shower, the pool and the ocean.
The metal: where a green mark comes from
Sterling silver is about 92.5% silver by weight. The remaining 7.5% is usually copper (Wikipedia, Sterling silver). Copper is the metal that can react with salts and acids in sweat and leave a greenish film on the metal. That film is what rubs onto skin. The silver itself is not the cause.
Plating is the layer that keeps your skin away from the copper. Mariqe pieces are described on the product page as platinum plated or 18k gold plated 925 sterling silver. While the plating is intact, skin touches the plating. Over months of daily wear, the layer thins at the points that rub most, and the metal underneath can then show through. This is true of every plated earring from every brand, and of plain sterling silver too. It is a normal characteristic of the metal, not a fault in a particular piece.
Skin chemistry plays a part. Some people sweat more, or have more acidic sweat, and see marks sooner. Two people can wear the same earrings and get different results.
Green or red: two different things
A green or dark mark on the skin is a cosmetic effect of copper. A red, itchy or blistered ear is something else, and it deserves a different response.
| What you see | Likely cause | What to do |
|---|---|---|
| A green or grey tint on the skin or the post, no itching | Copper in the metal reacting with sweat | Wash with soap and water. Wipe the earrings dry after wear |
| Dark marks on the silver itself | Ordinary tarnish | Clean gently, see the cleaning guide linked below |
| Red, itchy, burning or blistered skin, often 12 to 72 hours after wearing | Possible nickel allergy or another contact reaction | Stop wearing the earrings and see a doctor or dermatologist |
Cleveland Clinic lists earrings among the common sources of nickel allergy, notes that symptoms usually appear 12 to 72 hours after contact, and says a patch test is used to confirm it (Cleveland Clinic, Nickel allergy). It does not link nickel allergy to green skin. They are separate issues.
Simple habits that keep ears clear
- Wipe the posts and backs with a soft dry cloth after you take the earrings out.
- Put perfume, hairspray and lotion on first, and your earrings in last.
- Take them off before a shower, a swim or exercise, as you would with any plated jewellery.
- Store them dry, in the box they came in.
Our guide on how to clean moissanite jewellery without damaging the plating covers the cleaning step by step, and sterling silver with plating versus solid gold explains what you are buying and why the price differs.
If you already know your ears are sensitive
The Eterna listing, checked 15 October 2026, states the metal as 925 sterling silver with platinum or 18k gold plating. It does not state a nickel content, and we do not describe the pieces as hypoallergenic. If you have a diagnosed nickel allergy, ask your dermatologist about the specific metal before buying.
One policy point matters here. Pierced earrings cannot be returned for hygiene reasons unless they are defective. The 30 day return window applies to other items, so if you are unsure about your skin, a patch test before ordering is the safer route. The Lifetime Moissanite Warranty covers the stone, not the plating or the metal.
What this means for you
The gem is the stable part of the earring, and it is the part people notice. For the metal, a little care goes a long way: keep the posts dry and clean, and take the earrings off before water. If a faint green tint ever appears, soap and water removes it. Redness and itching are a different signal, and a doctor is the right next call.

Can a moissanite stone itself turn skin green?
No. Moissanite is silicon carbide and contains no copper. Any green mark comes from the metal around the stone, not the gem.
Will sterling silver earrings turn my ears green?
They can for some people. Sterling silver is 92.5% silver and the rest is usually copper, which can react with sweat. Plating adds a barrier while it is intact, and the mark washes off with soap and water.
Is a green mark the same as a nickel allergy?
No. A green mark is cosmetic and painless. A nickel allergy shows as red, itchy or blistered skin, usually 12 to 72 hours after contact, and a dermatologist can confirm it with a patch test.
Are Mariqe earrings hypoallergenic?
We do not make that claim. The listing states 925 sterling silver with platinum or 18k gold plating and does not state a nickel content. If you have a diagnosed metal allergy, check with your dermatologist first.
Can I return pierced earrings if they irritate my ears?
Pierced earrings cannot be returned for hygiene reasons unless they are defective. The 30 day return policy applies to other items, so a patch test beforehand is wise if your skin is sensitive.
