In custom projects, the design and content of a neckpiece can spring from many sources. The "Astrolabe" pendant, for instance, was based on the astronomical and navigational instruments of the middle ages. The "7 Sticks " pendant commemorates seven years of marriage, using seven unique sterling elements bound by an 18k ring.. The Steel Caged Marble was commissioned by a heart surgeon, based on early synthetic heart valve implants.
Personally charged materials often drive a project: the iron nails in the "Antique Nail Pendant" and the "Nail Nest", while the ash (cremains) in the "Reliquary Pendant" are framed on one side by the profile of a raven, an animal special to that family.
