Tube Settings

This week we've been making tube settings. We've used 5mm cubic zirconia's because they are very hard for a first setting and minimises the chance of breaking the stone. The tubing is 6mm outer diameter and 4.6mm inner diameter with a 0.7mm wall. Susan set this setting onto a ring shank. We then used a 5mm ball burr and the pendant motor to burr down into the tubing, polished and set the stone using the rub over technique...a voila!!
