Samsung Sterling Silver CZ Eternity Ring Cover
Lower concern. Sterling silver and cubic zirconia are not materials linked to PFAS.
This ring is sterling silver and cubic zirconia. Neither material is typically associated with PFAS-based treatments. The brand has no PFAS statement on record.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Nickel in alloy component
Sterling silver alloy typically uses copper, but some manufacturers include trace nickel or other metals. Nickel contact sensitivity affects 10-15% of the population; no specific testing published for this Samsung product. Risk is low but present for sensitive individuals.
Cubic zirconia durability and microparticle shedding
Cubic zirconia is harder than glass but softer than natural diamond; scratching and micro-fracturing occur with daily wear. Inhalation of shed zirconia dust during cleaning is theoretical; risk is minimal in normal use but not zero. No health incidents documented.
Setting stability and stone loss
Fashion jewelry settings may loosen with wear; a loose cubic zirconia stone poses no chemical hazard but a small choking risk if swallowed. Not a material toxicity issue but a mechanical failure mode to monitor.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Lead
No recalls or reports of heavy metal contamination in Samsung sterling jewelry. Modern jewelers typically use lead-free solder, but vintage or low-cost manufacturing may deviate. No on-record issue for this product line.

What it's made of and why it matters
This ring combines sterling silver (92.5% pure silver, 7.5% alloy, typically copper) with cubic zirconia (synthetic crystalline zirconium dioxide). Sterling silver is inert and non-leaching under normal wear. Cubic zirconia is a lab-created gemstone with no known off-gassing, leaching, or chemical reactivity during skin contact. Neither material requires chemical surface treatments that would introduce PFAS or other persistent hazards.
The brand's record and disclosure
Samsung's product line focuses on electronics and accessories; jewelry offerings are limited and do not have established third-party safety certifications or public sustainability disclosures specific to this ring. No recalls, safety incidents, or material controversies are on record for Samsung jewelry. The brand's silence on material sourcing and heavy metal testing is typical for mass-market fashion jewelry but does not indicate a known problem.
How it compares in its category
Sterling silver and cubic zirconia rings are standard consumer jewelry materials with decades of documented use history. Cubic zirconia is lower-risk than lab-created alternatives like synthetic moissanite (which can contain residual silicon carbide dust). Sterling silver is more stable than plated alternatives, which risk nickel leaching or coating flaking. This product sits in the mainstream safety tier for affordable fashion jewelry.
If you buy it
Clean gently with mild soap and water; avoid harsh solvents or ultrasonic cleaners that may loosen the stone setting. Sterling silver will tarnish over time (natural oxidation, not a hazard) and can be polished or treated with commercial tarnish removers. Cubic zirconia scratches more easily than natural diamonds and will appear cloudy after 2-3 years of daily wear; replacement is cosmetic, not safety-driven. Remove during vigorous exercise or chemical exposure (chlorine, harsh cleaners) to preserve the setting.
