Helped out by doing a pair of 5/6 grade games last night. Checked over all the players from the turret of the midcourt sideline area prior to the game. No jewelry that I could detect.
Then, midway through the first quarter, I halt play to instruct a player to remove her rings. That's right, rings. Silver. On all four fingers of one hand.
She showed me her hands. They weren't rings. She was wearing glossy SILVER nail polish!
SILVER nail polish! Glimmering under the bright gym lights, they sure looked like rings to me.
Since it was a small gym, everyone was able to hear my reaction and got a good-natured laugh out of the whole brief episode.
