- Diamond Saw: A high-precision diamond saw is used to cut the rough tanzanite crystal into smaller pieces or to shape the gemstone.
- Dop Stick: A dop stick is a wooden or metal rod used to hold the tanzanite crystal securely during cutting and polishing.
- Faceting Machine: A faceting machine is used to create the facets on the tanzanite gemstone, giving it its final shape and brilliance.
- Polishing Equipment: Polishing equipment, such as polishing wheels and compounds, is used to refine the gemstone’s surface and achieve a lustrous finish.
Step-by-Step Guide to Cutting Tanzanite
The process of cutting tanzanite involves several meticulous steps:
1. Rough Selection: The first step is selecting high-quality rough tanzanite crystals with good color, clarity, and size.
2. Orientation: The crystal is carefully oriented to determine the best cutting direction based on its color and cleavage planes.
3. Preforming: The rough crystal is cut into smaller pieces using a diamond saw to remove unwanted material and create a basic shape.
4. Blocking: The preformed pieces are further cut into smaller, more manageable pieces called “blocks.”
5. Bruting: The blocks are shaped into the desired gemstone shape using a diamond saw or a faceting machine.
6. Faceting: The gemstone is mounted on a dop stick and placed on a faceting machine. The machine’s diamond-coated wheels are used to create facets on the gemstone, giving it its final shape and brilliance.
7. Polishing: The gemstone is polished using various polishing compounds and equipment to achieve a smooth, lustrous surface.
Considerations for Cutting Tanzanite
When cutting tanzanite, several factors must be considered to ensure a successful outcome:
- Cutting Direction: The cutting direction must be carefully chosen to avoid cleaving the gemstone along its cleavage planes.
- Heat Management: Tanzanite is sensitive to heat, so it is essential to use water or coolant during cutting and polishing to prevent damage.
- Facet Design: The facet design plays a crucial role in maximizing the gemstone’s brilliance and fire. Cutters must consider the gemstone’s shape, size, and color when designing the facets.
Safety Precautions for Cutting Tanzanite
Cutting tanzanite requires strict adherence to safety precautions:
- Proper Eye Protection: Always wear safety goggles or glasses to protect your eyes from flying debris and sharp edges.
- Respiratory Protection: Use a dust mask or respirator to avoid inhaling harmful dust particles generated during cutting and polishing.
