Correction note for “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: retain the wording beginning “Sapphire is very hard to scratch but can chip or crack…” 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. Keep the stated question separate from any broader claim.
