You know that sinking feeling you get when you take a piece of jewelry out of the ultrasonic and stones are missing-and your cleaning solution is hard to see through? Now, thanks to JA Certified Master Bench JewelerT Jeffrey Mathews of Jeffrey Mathews Designs, Dallas, Texas, you can avoid that feeling by using his quick and simple process to locate and retrieve them.

Select a standard drinking glass.

Lower it bottom first toward the bottom of the ultrasonic tank.

While moving the glass around the tank and looking through the bottom of the glass, locate the missing gemstone.

Once the gemstone is found, remember its location and carefully remove the drinking glass from the tank.

Rinse and dry the glass.

Melt a generous portion of soft red sprue wax onto the bottom of the glass.

Allow the wax a minute to cool (or run cold water over it).

Replace the glass into the ultrasonic tank at the location of the missing gemstone. Gently lower the glass over the gemstone, allowing the soft and sticky wax to "pick it up."

Remove the glass from the ultrasonic tank.

Remove the gemstone from the wax, clean it, and reset it.
