Ion plating (IP)
On the label: Ion plating · Plating and finish
What it is
A form of PVD used on steel watches and jewelry; the same vacuum process, marketed under another name.
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
3 PubMed papers mention it with jewelry, allergy, eyewear or UV; the three most recent:
- Safety and efficacy of nano lamellar TiN coatings on nitinol atrial septal defect occluders in vivo · Materials science & engineering. C, Materials for biological applications, 2013
- Nano structured physical vapor deposited coatings by means of picosecond laser radiation · Journal of nanoscience and nanotechnology, 2011
- High-reflectivity HfO2/SiO2 ultraviolet mirrors · Applied optics, 2002
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.
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.
