APM Castings — Perfection Every Time

Stone-Setting

Certified master setters working across natural and lab-grown diamonds and coloured gemstones, with an in-house testing lab that verifies every stone.

Comprehensive stone-setting expertise

At the heart of our operation is a casting house staffed with master artisans who bring decades of specialised experience to every project. Our team works across the full spectrum of diamonds and gemstones, and the setting techniques each one demands.

Our certified master setters work with

  • Natural diamonds of all grades and cuts
  • Laboratory-grown diamonds with exceptional clarity
  • Precious gemstones requiring delicate handling
  • Semi-precious stones with unique characteristics

Using setting techniques including

  • Invisible settings that showcase stones without visible metal
  • Channel settings for elegant stone alignment
  • Prong, bezel, pavé and tension settings tailored to your specification

Advanced authentication technology

Our testing laboratory uses professional-grade equipment, because in a market where lab-grown and simulant stones circulate freely, a setter who cannot verify what they are setting is a liability.

  • Diamond testing instruments that precisely differentiate natural from laboratory-grown
  • Detection systems for simulants including moissanite and cubic zirconia
  • Refractive index and density testing for comprehensive gemstone verification
  • Optical analysis tools to assess cut quality and precision
