Here's a photo of what is affectionately called the "Reitz Chalice", owned by my diocese. The stones were gifted from Josephine Reitz upon her death about a hundred years ago. The stones alone were valued at $100k when the chalice was finished in 1930. It's stored at a "secure location" now and sees use every few years. We have to pay an arm and a leg for them to bring it in a Brinks truck while dudes with AR-15s provide security.
