Gaspare thanks for your info. As you told about the momento mori rings and the use of the beloved departed's hair, I had to think about the artpieces , around 1800-1900 , inwich are used the deceased's( complete) hair . They are "application-works" behind glass, like paintings, often look like " decorative flower bouquets" .
Till yet, I haven't encountered a momento mori ring , but who knows... Big Grin
Thanks again,
Benten
