Ashes ...To Stone?

I came across this odd piece of news reading today's The Express, a publication of The Washington Post:

Here's one practical way to keep a deceased loved one close to your heart: Have his or her ashes mixed with artificial stone and made into jewelry that you can wear around your neck. The service, offered by a Japanese company, produces round pendants that can be purchased in nine different colors and are priced at about $1,100 each.

Ok. But I wonder what will be the feeling of the owner when the pendant is lost or stolen?
