Sterling silver is an alloy of silver containing 92.5% by mass of silver and usually 7.5% by mass of copper. The sterling silver standard has a minimum millesimal fineness of 925. The sterling alloy originated in continental Europe and was being used for commerce as early as the 12th century in the area that is now northern Germany. William Henry uses the latest state-of-the-art casting equipment to create mesmerizing pieces that are often considered par with our hand-carved work.
Kevlar is the registered trademark for a synthetic fiber developed at DuPont in 1965. This high-strength material was first commercially used in the early 1970s as a replacement for steel in racing tires. Typically it is spun into ropes or fabric sheets offering many applications, ranging from bicycle tires and racing sails to body armor. Because of its high tensile strength-to-weight ratio it is 5 times stronger than steel.
Kevlar is also a well-known component of personal armor such as combat helmets, ballistic face masks, and ballistic vests. William Henry uses woven Kevlar to create necklaces and bracelets which offer unparalleled strength and comfort.
