Sterling silver, 9k gold, 10k gold, 14k gold, and 18k gold tubing is chosen from foundries with the rigid quality control that Pearl requires. Upon arrival at the Pearl workshops, each length of tubing is carefully inspected and any that do not meet Pearl's stringent specifications are rejected. Only after the raw materials are inspected and approved, can the process of making a flute begin. Each step is monitored and quality checks are performed constantly. Nothing is automatic.
Every operation is controlled by the eyes and hands of a skilled craftsman.
The final assembly brings all the carefully crafted components together in their final purpose. The finest springs, felts, corks and pads are made to Pearl's exacting specifications. There are no compromises. Only when every test for mechanical function and playing qualities are passed, can it leave the workshops at Pearl. There is wide debate about the acoustic benefits of gold plating on a silver instrument.
