Core Responsibilities

Primary Functions

Expertly operate multi-speed polishing lathes, lapping machines, and various hand-held flex-shaft tools to apply precise finishes, ranging from high-mirror to satin, on diverse and complex jewelry designs.
Meticulously select and apply the correct sequence of polishing compounds, wheels, buffs, and abrasives based on the specific metal type (e.g., platinum, 18k gold, palladium, silver) and the desired final texture.
Execute pre-polishing and cutting stages to effectively remove scratches, tool marks, and surface imperfections from raw castings and assembled pieces without compromising structural integrity or design details.
Perform comprehensive quality control inspections under magnification before, during, and after the polishing process to identify and correct any flaws such as porosity, file marks, or uneven surfaces.
Handle high-value, one-of-a-kind, and bespoke jewelry pieces with extreme care and precision, ensuring the security and preservation of delicate settings and precious gemstones.
Master a variety of advanced finishing techniques, including satin, matte, brushed, and sandblasted finishes, and apply them consistently according to detailed work orders and design specifications.
Interpret technical drawings, job envelopes, and verbal instructions from designers and jewelers to fully understand the required finishing outcomes for each individual piece.
Conduct final cleaning of polished jewelry using ultrasonic cleaners, high-pressure steamers, and appropriate solutions to ensure every item is pristine and free of any residual compounds.
Diligently maintain all polishing equipment, including changing buffs, dressing wheels, and ensuring the proper function of dust collection systems to maintain a safe and efficient work environment.
Systematically manage and organize the inventory of all polishing supplies, including compounds, wheels, and other consumables, and communicate replenishment needs to the supply manager.
Adhere rigorously to all company and industry safety protocols, including the proper use of personal protective equipment (PPE) like safety glasses, dust masks, and protective finger coverings.
Employ masking techniques using tape or other materials to protect delicate gemstones, intricate engravings, or contrasting finishes on a single piece during the polishing process.
Skillfully refine and recover precious metal dust and scrap from polishing machines, bench sweeps, and filters to minimize waste and maximize material reclamation.
Collaborate proactively with bench jewelers and stone setters to address any issues that may impact the finishing process, ensuring a seamless workflow from creation to completion.
Document all work performed on job travelers or in digital tracking systems to maintain accurate production records and ensure accountability for each step.
Apply tumbling techniques, using magnetic tumblers or rotary barrels with appropriate media, for mass finishing of certain components while maintaining quality standards.
Perform light bench work, such as minor surface repairs or touch-ups, to prepare pieces for polishing or to correct issues discovered during the finishing stage.
Stay current with emerging finishing technologies, materials, and techniques within the jewelry industry to contribute to process improvement and innovation.
Provide accurate time estimates for polishing tasks to assist in production scheduling and workflow management, ensuring deadlines are consistently met.
Mentor and provide guidance to apprentice-level polishers, sharing knowledge of best practices, safety procedures, and advanced techniques to foster skill development within the team.
Execute final lapping on flat surfaces to achieve perfectly sharp edges and planar reflections, a critical skill for high-end and geometrically complex jewelry.

Secondary Functions

Assist with special finishing projects and the development of samples for new jewelry collections, providing expert feedback on feasibility and techniques.
Contribute to the continuous improvement of finishing processes and the refinement of standard operating procedures for quality and efficiency.
Collaborate closely with bench jewelers, stone setters, and design teams to troubleshoot finishing challenges and ensure design integrity is maintained in the final product.
Participate in production planning meetings to provide valuable input on timelines and potential finishing complexities for upcoming jobs and collections.
