Instructions
Pick up the rough ruby in the tip of the cross-locking tweezers. Center the ruby so the largest area is held by the tweezers.
Unscrew the screw on the top of the jeweler's third hand. Place the handle of the cross- locking tweezers into the handle slot and tight the screw securely. A third hand is a type of small vise used by jeweler's to hold objects. The construction of the mechanism allows mobility of the tweezers as an arm so all sides of the ruby are workable without removing it from the tweezers.
Plug in a Dremel rotary tool and attach a small abrasive tip. Look at the rough ruby and determine what type tip is needed to remove the unwanted minerals and stone surface.
Place the abrasive tip on the area and begin grinding away the unwanted mineral and stone. Watch closely while grinding to avoid damaging the ruby.
Brush the dust off periodically so a clear view of the rough ruby surface is always seen.
Change grinding tips as necessary to remove the different types of deposits.
Remove the ruby from the cross-locking tweezers and reposition ruby. Secure into place. Begin grinding away minerals and rock surface.
Small rubies may break away while cleaning a larger rock. Set them aside and continue the grinding process until all stones are set free.
Either process the rubies at home with a rock tumbler and Dremel buffing bit or take the them to a jeweler for processing.
