Ashley Gilreath created this remarkable necklace from tiny photos of her ancestors. "I casted dollhouse frames from sterling silver and bronze, and printed my family directly onto the glass," she says. "I Am Who They Were." (Thanks, Lindsay Winterhalter!)

Today I found myself at a street-market in Soho (the one in London), at a stall belonging to Amelia Parker, a jewelry maker who salvages fragments of century-old clay pipes from the banks of the Thames. Clay pipes were once the equivalent of cigarettes, cheap, semi-disposable tobacco-distribution systems, and as they were very brittle, they were tossed out by the tens of thousands, forming a lightweight layer of river detritus that still washes up on the riverbanks in London.
