Morganite
On the label: Morganite · Gemstone
What it is
Pink to peach beryl; the pink is often strengthened by heat. Mohs 7.5 to 8.
Gemstones: Natural gemstones, as mined and cut. Hardness (Mohs scale) says what scratches what; treatment (heat, oil, dye) must be disclosed under FTC rules.
In the research
2 PubMed papers mention it with jewelry, allergy, eyewear or UV; the three most recent:
- [Spectroscopic characteristics study of morganite from Mozambique] · Guang pu xue yu guang pu fen xi = Guang pu, 2014
- Use of laser induced breakdown spectroscopy in the determination of gem provenance: beryls · Applied optics, 2008
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 gemstones
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.
