Sterile Ruby Bead (6mm)

Mindblowing fact number 1: Rubies glow under UV light. Mindblowing fact number 2: Rubies are biocompatible and bioinert. These 6mm sphere-shaped rubies are carefully inspected, cleaned, and sterilized. They are individually packaged in sterile autoclave pouches. When flashed with a strong light source (ideally UV), they will visibly glow red. Larger sizes glow more visibly. There is no significant afterglow: these are fluorescent, not phosphorescent.
