This exceedingly yummy thimble "charm" bracelet is up for auction on eBay as I write this. The bracelet is not sterling silver but the thimbles are.
The auction ends March 6th, 2007, at 19:54:41 PST. The starting bid is set at US$199.99, and there's a BuyItNow price of US$349.99. Shipping is $5.00. There are closeups of the individual thimbles on the auction page. The thimbles appear to have been pierced to accommodate a silver loop to attach to bracelet. Ouch!
The bracelet was donated to the non-profit organization, Whiskers Rescue, Inc., "dedicated to humanely controlling the stray and feral cat over population."
