The Burgundy Red, Turquoise Blue, and Heather Pink ones all have a silvertone body, 
and adjust between 18 and 20" around
(best for necks under 16" so that they lay flat under the collar bone)

the White one is has a gold tone body,
and adjusts between only 15 & 18" around
(best for necks under 14" so that they lay flat under the collar bone)
