For some reason, I was craving pizza, I wanted to try out a new interesting outline, and I was reading some old Sherlock Holmes. I figured this would be the perfect name. There will always be some tiny random windows, but barring that, this design works in materials from quartz to rutile (RI = 1.54 - 2.62) with no changes. Suggested length = 8-12 mm
