Italian 925 Rhodium-Plated Sterling Silver vs. 14k Gold Vermeil vs. Solid 14k Gold Tennis & Miami Cuban Chains: Gram Weights, Box-Lock Clasps & Tarnish Prevention
What each metal weighs, costs and needs, and why a box-lock clasp matters on heavy Cuban links.
Executive Summary & Lab Winner
925 sterling (92.5% silver) with rhodium plating is the value pick and resists tarnish well; 14k gold vermeil is a thick gold layer over sterling and needs gentle care; solid 14k gold (58.3% gold) weighs ~26% more than the same chain in sterling and costs far more per gram. Box-lock clasps are the secure choice on 8mm+ Cuban links.
