Gemstones have a varied range including ruby, emerald, quartz, agate, and crystal. Yellow sapphire and blue sapphire are used in precious jewellery. They both are precious and semi-precious.
For the dressing process, the cracks of stone and its colour is taken into consideration. Before working on the subject it is important to draw an outline sketch of it using own imagination. Then the sketch drawn on paper is replicated to the stone with accuracy using the pencil. Afterwards grinder machine is used for roughly cutting the stone with help of water.
The small diamond tools are used to carry out the carving process. These tools create apt detailing to give the sculpture a definite shape. The polishing process of the sculpture is done using green buff. A buffing cloth is attached to the motor and gradually a green-coloured powder is applied to the surface.
Finally, the sculpture is washed with clean water and oiling is done in order to enhance the colour and shine of the piece. It also gives a softness to the sculpture. Gemstones like blue sapphire, ruby or emerald are polished with sandalwood and oil.
The hardship and full concentration of mind are used in transforming a stone into a sculpture.
