What it is
Gold plating over sterling silver, at least 2.5 microns thick and at least 10k gold, by the FTC definition. Both layers are precious metals, which is why vermeil is the hypoallergenic choice among gold-colored pieces.
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
No PubMed papers mention this material with jewelry, allergy or eyewear; that is usual for findings and trade terms.
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.
