Which is an allowed earring size?

• A. 1-2 mm
• B. 8-10 mm
• C. 10-12 mm
• D. 4-6 mm

Answer: (D)

Uniform appearance and safety guide jewelry to conservative, easily maintained sizes. An earring in the 4-6 mm range stays unobtrusive yet clearly recognizable as jewelry, which is the aim of the standard: a small, plain stud that won’t stand out or create snag hazards. Larger sizes like 8-10 mm or 10-12 mm are too conspicuous and violate the expected uniform look. A very small size such as 1-2 mm may not meet the standard’s typical visibility or presence requirements for jewelry in uniform wear. So, 4-6 mm fits the allowed range best.
