Case 39 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear · source wording exercise

Clarification for “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: the point beginning “Sapphire is very hard to scratch but can chip or crack…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: source wording. Retain the source wording beside any paraphrase.
