Case 32 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
Clarifying question: what does daily wear mean for you? Desk work, manual labour or sports change the answer. For desk use, sapphire's scratch resistance is the main benefit. For work with frequent knocks, a slightly domed acrylic that you can polish may last longer in practice, despite the scratches.
