Why Solid 14k Gold Is the Engineering Standard for Tennis Bracelets
Pure 24k gold is far too soft to hold diamonds securely under daily movement. 14k gold (58.5% pure gold alloyed with strengthening metals) offers significantly higher tensile strength and scratch/bend resistance than 18k gold (75% gold)—which is critical for the 50+ articulated hinge pins and safety box clasp of a tennis bracelet.
