  • A shiny gray steel that is similar in color to platinum
  • Harder than stainless steel (read: it’s very durable)
  • An alloy composed of approximately 67% Cobalt, 27% Chromium, and 6% Molybdenum
  • Renowned in the metals industry for its superb wear resistance, and is used for artificial joints and dental implants. As such, the metal is highly biocompatible, i.e. hypoallergenic!
  • While Cobalt-Chrome has an incredible luster after high polish, it does, however, have certain limitations in jewelry making. The high level of wear resistance also causes it to resist tools, making it very difficult to drill holes, set stones, or size in a traditional manner. The best use for this metal can therefore be found in pendants, earrings, cufflinks, necklaces, and bracelets, etc. that do not require sizing and designs that showcase the metal versus stones. Stones, when needed, can be riveted or glued in place.
  • Another benefit of Cobalt-Chrome is its susceptibility to blackening. Blackening is done through a chemical process that creates a black oxide layer providing a wonderful contrast with platinum, palladium, and gold alloys.
  • Cobalt chrome is also budget-friendly—plain bands run between $300-$500.
