This Waterford Crystal thimble is available from a variety of retailers at a variety of prices. House of Ireland has an OK price (US$45.01) currently, though the U.S. price fluctuates with the exchange rate.
I got my own Waterford Crystal thimble ages ago when they were only US$26.00. It doesn't have the little etched mark, though it was purchased retail from a reputable retailer. I think maybe that was before they marked everything the way they do now(?). It looks exactly the same as this one and feels like all the others I've looked at.
