Flat Laps: Used for creating perfectly flat surfaces or for polishing flat-backed cabochons, flat laps are essential for precision work. They utilize interchangeable diamond laps of various grits.
Grinding Wheels: Made from diamond or silicon carbide, grinding wheels come in different grits from coarse to fine. They are crucial for removing significant material and refining the stone’s shape.
Polishing Machines: Unveiling Brilliance
The final step in bringing a stone to life is polishing, which reveals its inherent luster and brilliance. Dedicated polishing machines are vital professional lapidary supplies for achieving a mirror finish.
Vibratory Tumblers: While often associated with rock tumbling, industrial-grade vibratory tumblers are used for bulk polishing of smaller stones or for the initial stages of polishing larger pieces.
Polishing Laps: Used on cabochon machines or flat lap machines, polishing laps are typically made of felt, leather, or specialized composite materials. They are used with polishing compounds to achieve a high-gloss finish.
The Heart of the Process: Abrasives and Polishing Agents
The magic of lapidary often lies in the abrasives and polishing agents used. These consumable professional lapidary supplies do the actual work of removing material and creating a smooth, reflective surface.
Diamond Abrasives: The Industry Standard
Diamonds are the hardest known natural material, making them the most effective abrasive for cutting and grinding gemstones.
Diamond Grits: Available in a wide range from very coarse (e.g., 60-80 grit) for rapid material removal to ultra-fine (e.g., 14,000-50,000 grit) for pre-polishing. Selecting the correct progression of grits is vital.
Diamond Paste/Slurry: Used on polishing laps, diamond paste or slurry provides a consistent abrasive medium for achieving extremely smooth surfaces and preparing for final polish.
Silicon Carbide: Versatile and Effective
Silicon carbide is another widely used abrasive, particularly for grinding wheels and sanding belts. It is excellent for shaping and smoothing various types of stones.
Silicon Carbide Wheels: Often found on combination grinding and polishing units, these wheels come in different grits for progressive material removal.
Sanding Belts: Used on belt sanders, silicon carbide belts are effective for shaping and smoothing cabochons and other free-form pieces.
Polishing Compounds: The Final Sheen
Specialized compounds are used with polishing laps to bring out the ultimate shine in a gemstone. The choice of compound depends on the stone’s hardness and composition.
Cerium Oxide: A very popular and effective polishing agent for most quartz varieties and softer stones.
Tin Oxide: Often used for harder stones and for achieving a high luster on jade and other tough materials.
Alumina: Aluminum oxide compounds are also used for polishing a variety of gemstones, often chosen for their specific abrasive properties.
Precision and Artistry: Faceting Equipment
For those aspiring to create multi-faceted gemstones, specialized faceting equipment is paramount. These professional lapidary supplies allow for precise angle control, critical for optimal light performance.
Faceting Machines: Engineering Light
Faceting machines are precision instruments that allow the artisan to cut and polish each facet at exact angles.
Mast-Type Machines: These are common, featuring a central mast that holds the cutting head and allows for adjustments in height and angle.
Platform-Type Machines: Offering a different configuration, these machines provide stability and often have digital readouts for extreme accuracy.
Dops and Dop Wax: Holding the Stone
Dops are small sticks or metal pieces used to hold the gemstone securely while it is being faceted. Dop wax, a specialized adhesive, attaches the stone to the dop.
Dops: Available in various shapes and sizes to accommodate different stone geometries.
Dop Wax: Designed to hold the stone firmly during grinding and polishing, yet allow for easy removal without damaging the gem.
Faceting Laps: The Precision Surface
Faceting laps are flat disks, typically made of copper, tin, or composite materials, onto which diamond abrasives are applied. They are crucial for creating perfectly flat and precisely angled facets.
Pre-Polishing Laps: Used with fine diamond grits to prepare facets for final polishing.
Polishing Laps: Designed to be used with diamond paste or polishing compounds to achieve the ultimate shine on each facet.
