Skip. Waterproof ring with undisclosed coating raises PFAS concern.
Smart NFC rings require waterproof treatment to function; Samsung provides no material or coating specifications here. Waterproof coatings commonly use PFAS without disclosure in budget electronics.

The full breakdown
What it's made of and why it matters
This ring uses an unspecified metal alloy with an undisclosed waterproof coating or treatment. The coating composition is critical because waterproofing in jewelry typically relies on Teflon-family coating or other surface treatments that may contain PFAS compounds to repel water. Without manufacturer disclosure of the alloy type (stainless steel, titanium, nickel content) or coating chemistry, you cannot assess leaching risk or allergenic potential from the metal base itself. Waterproof coatings on wearables that contact skin continuously pose a particular concern because micro-abrasion from daily wear could expose underlying materials.
The brand's record and disclosure
Samsung does not publicly disclose material composition or PFAS presence for this specific smart ring product. The company has not published third-party testing results, material safety data sheets, or certifications (such as OEKO-TEX or Nickel Release directives compliance) for this item. Samsung's general environmental commitments do not extend transparent disclosure to wearable electronics at the component level. The wholesale listing itself provides no safety documentation, certificates of origin, or batch traceability.
How it compares in its category
Smart rings in this price tier and distribution channel typically do not undergo independent dermatological or material testing. Competitors like Oura Ring publish material specifications and claim nickel-free construction, though third-party verification is limited industry-wide. This wholesale product lacks any equivalent transparency or certification standard, making direct safety comparison impossible. Most consumer-grade smart jewelry does not disclose waterproof coating chemistry, which is an industry-wide gap rather than a Samsung-specific failure.
If you buy it
Wear the ring only if you have no known nickel sensitivity; contact dermatitis is the primary foreseeable risk from unspecified metal alloys on continuous skin contact. Do not submerge the ring or expose it to hot water, as thermal stress may degrade the waterproof coating and release particles or leachates. Replace the ring if the coating visibly cracks, discolors, or peels. Stop use immediately if you experience localized itching, redness, or irritation under the ring; this may indicate nickel release or coating breakdown.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Nickel leaching from unspecified metal alloy
Continuous skin contact with an undisclosed alloy on a waterproof wearable creates high probability of nickel release, especially if the coating degrades. No material certificate or nickel-release testing is available.
Waterproof coating degradation and leachate release
Daily wear, friction, and exposure to water and sweat will gradually abrade any surface coating. Unknown coating composition means you cannot predict what contaminants (including PFAS or other fluorochemicals) might leach as the coating fails.
Contact dermatitis from coating or metal
Wearables with undisclosed materials and coatings commonly trigger localized allergic reactions. The ring's continuous contact and moisture-trapping geometry increase risk compared to non-wearable jewelry.
Lack of supply chain transparency and batch control
Wholesale bulk products often vary between batches in coating application, metal composition, and manufacturing controls. No batch testing or lot tracking is disclosed, making it impossible to know consistency.
Unknown fluorochemical compounds in waterproof treatment
Waterproofing on metal jewelry frequently relies on PFOA, Teflon-type coating, or other fluorinated polymers; Samsung has not disclosed the specific chemistry used, and third-party analysis is not available for this product.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
