Yellow gold
On the label: Yellow gold · Alloy
What it is
Gold alloyed with silver and copper in roughly equal parts to keep the gold color while hardening it.
Alloys: Mixtures of metals used because pure gold and silver are too soft to wear; the other metals set the color and the hardness, and sometimes the allergy question.

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.
