Rock polishing is achieved via a process called 'tumbling'. A tumbler consists of an electric motor, a barrel, and a frame with rollers. A pulley and a belt connect the rollers to the motor. To begin with, the barrel is filled up to almost three quarters with stones of about 1 inch in diameter. Silicon carbide is then added in a proportion that is half the total load in the barrel. Water is also added. The basic procedure is to tumble the rocks with progressively finer grits and polishes until the desired shape and shine is achieved. As the barrel rotates, its contents collide, wearing down the stones. The stones then begin to erode. The rate at which the stone erodes will depend on its characteristics. Every day, stop the machine, remove some stones, and wash them under clean water. Then allow them to dry and inspect them with a small magnifying glass under bright light. Clean out the sludge in the barrel. If the stones are pitted or cracked, return them to the tumbler, add the right amount of silicon carbide and water, and repeat the process. When your samples do not reveal these pits, cracks, and hairlines, remove all the stones. It may take 4 to 6 weeks to finish a batch. Once the stones are perfected, comes the final part. A tablespoon of cerium oxide per pound of stones is to be added. Tumble for another week.
Unique designs and works are being followed by various regions and cultures.

All regions have different trends and their designing is unique.
Another reason why tanzanite jewelry should be worn carefully is because it can scratch very easily when it comes into contact with other objects. As such, keep this beautiful jewelry for those special occasions.
