Oxidized (antiqued) silver
On the label: Oxidized silver · Plating and finish
What it is
Sterling deliberately darkened with a sulfide solution to shadow the recesses; the raised surfaces polish bright with wear.
Plating and finishs: A thin layer of one metal over another. The layer's thickness, written in microns, decides how long it lasts; US law sets minimums for what may be called gold-filled or vermeil.
In the research
1 PubMed papers mention it with jewelry, allergy, eyewear or UV; the three most recent:
- Surface-Oxidized Polymer-Stabilized Silver Nanoparticles as a Covering Component of Suture Materials · Micromachines, 2022
A paper is a paper, not a verdict: titles are listed so you can read them, and a study on one fabric or one filter says little about the piece in your hand.
Pieces whose listing names it
1 on the siteMatched from the words in the supplier's listing; the full material line is on each product page.
Other plating and finishs
Clasp & Lens describes materials from the public record and does not appraise, grade or test pieces; what a listing states is the supplier's statement. If a piece causes a rash, take it off; a reaction that spreads or blisters is a doctor's question, and sunglasses are no substitute for impact-rated eye protection where that is required.
