I produced a series of charms/pendants based on the symbols from my book. And the first two offerings (the Holy Spirit and the Forgiveness charms/pendants) were available from a company called Shapeways between July 2011 and July 2012. It was a limited time offering, which is now over. For the time being, no jewelry is up for sale.
