Case 103 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear · comparison exercise

Correction note for “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: retain the wording beginning “Acrylic scratches easily but flexes, rarely shatters, and light scratches…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Make the basis of a comparison explicit before interpreting it.
