William Henry P27 Carbon Spark

Sometimes the small details make all the difference. The William Henry P27 Carbon Spark is a simple and understated pendant, but not one to be underestimated. Rendered in sterling silver with William Henry’s hand-cut ‘leaf pattern’, and inlaid with ‘crushed’ carbon fibre. The chain is an antique finish sterling silver.

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 their hand-carved work.

Carbon fibre is a material consisting of microscopic fibres composed mostly of carbon atoms. The carbon atoms are bonded together in crystals that are more or less aligned parallel to the long axis of the fibre. The crystal alignment gives the fibre high strength-to-volume ratio. Several thousand carbon fibres are bundled together to form a tow, which may be used by itself or woven into a fabric. Carbon fibre’s properties, such as high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion, make them very popular in aerospace, civil engineering, military, competition sports. William Henry uses the highest grade, and beautifully textured carbon fibre for its collections of jewellery, knives, money clips and cufflinks.
