A razor never cut so cute before this solid 18k gold blade pendant. The blade measures 30mm x 17mm x 2.5mm at it's thickest point. A substantial hunk of solid yellow gold weighing in at .4 oz of solid gold. Goldfinger thinks it's worn best on a short 16" bead chain but you may choose 18" if you prefer. While the pendant and closed jump ring are solid 18k, the bead chain is solid 14k.
