I shall pass over this one in discrete silence.
From the website:
Cremation jewelry is, simply put, jewelry that contains some of the cremated ashes of a deceased family member or loved ones. Cremation jewelry has many names and comes in a variety of forms, but no matter the words used, cremation jewelry is among the newest and most popular ways to memorialize loved ones.
(My thanks to the blogger whose site I saw this on, though now I can’t remember where!)
