Crystal (leaded glass)
On the label: Crystal · Glass, crystal and resin
What it is
Glass with lead oxide (or, in newer 'lead-free crystal', barium or zinc) for extra sparkle and weight; Swarovski-type stones are precision-cut crystal, not quartz.
Glass, crystal and resins: Glass, crystal and enamel: the honest, inexpensive end of jewelry, when called what it is.
Wikidata: Solid material whose constituent atoms, molecules, or ions are arranged in an ordered lattice extending in all three spatial dimensions. Q43533 →

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.

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.
