Case 40 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear · source wording exercise

Method note for “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: use “Sapphire is very hard to scratch but can chip or crack…” as a row heading in a proposed working record. Put the statement, its supporting source or measurement, and any unresolved detail in separate fields. This proposes a format; it supplies no additional evidence. Retain the source wording beside any paraphrase.
