Basic Lapidary Steps

Preforming

Preforming is the initial step in lapidary work, where rough gemstones are shaped into manageable pieces. Using saws and trim saws, artisans remove excess material, preparing the stones for further shaping and detailing.

Shaping and Grinding

Shaping involves transforming preformed stones into desired shapes using grinding wheels and shaping discs. Artisans meticulously grind the gemstones, ensuring precision and symmetry in the final product.

Sanding and Polishing

After shaping, gemstones undergo sanding and polishing processes to achieve a smooth and lustrous surface. Various grits of sandpaper and polishing compounds are used to refine the surfaces, enhancing the stone’s brilliance and shine.

Advanced Techniques

Inlay Techniques

Inlay techniques involve setting small, shaped pieces of gemstones into cavities or designs on larger stones. This intricate method allows artisans to create detailed patterns and designs, adding depth and texture to jewellery pieces.

Drilling and Piercing

Tumbling Techniques

Tumbling is a method of polishing multiple gemstones simultaneously. Stones, abrasive grit, and water are placed in a tumbling machine, which rotates, causing the stones to rub against each other, resulting in polished surfaces. This technique is ideal for small stones and beads.

Expert Tips and Tricks

Enhancing Colour and Clarity of Gemstones

To enhance the colour and clarity of gemstones, lapidary artists often employ techniques like heat treatment and irradiation. These processes can intensify natural colorus and improve clarity, resulting in gemstones of higher value. However, it's crucial for artisans to disclose any treatments done to maintain transparency and ethical practices.
