Case 54 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear · source wording exercise

Limit of the answer in “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: “Sapphire is very hard to scratch but can chip or crack…” is an excerpt from the discussion, not an independent verification. A reader needs the relevant original material before treating an interpretation as established. Review focus: source wording. Retain the source wording beside any paraphrase.
