What it is
Element 22: light, strong, grey, does not corrode and is used in implants, so it is one of the safest metals for sensitive skin. It cannot be soldered or resized by ordinary jewelers.
Metals: Solid metals: what the piece is made of all the way through. Purity is written as karat (gold) or parts per thousand (925 silver, 950 platinum).
Wikidata: Chemical element with symbol Ti and atomic number 22. Q716 →
In the research
2,134 PubMed papers mention it with jewelry, allergy, eyewear or UV; the three most recent:
- Datasets of small intestine and systemic immune components, transcriptomics in jejunal tissue, fecal 16S rRNA gene amplicon sequences, and fecal and plasma metabolome, in young fem · Data in brief, 2026
- Coupled Effects of Reprocessing, TiO(2), and Fused Filament Fabrication on Polylactic Acid Weathering Durability: A Critical Review · Polymers, 2026
- Effect of Ultraviolet Photofunctionalization on Implant Stability and Marginal Bone Loss in Early-Loaded Dental Implants: A Triple-Blind Randomized Split-Mouth Clinical Trial · Cureus, 2026
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 metals
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.
