The Basics of Sandpaper

Sandpaper, also known as abrasive paper, is a versatile tool used for smoothing surfaces and removing material. It consists of a backing material, such as paper or cloth, coated with abrasive particles. The abrasive particles, known as grit, come in different sizes and materials, allowing for various levels of abrasion. Common types of sandpaper include silicon carbide, aluminum oxide, and garnet.

Grit Sizes and Their Applications

Grit size refers to the number of abrasive particles per square inch of sandpaper. The higher the grit number, the finer the abrasive particles and the smoother the finish. In jewelry making, different grit sizes are used for specific tasks:

  • Coarse Grit Sandpaper (60-100): Ideal for shaping and removing excess material from metal or gemstones.
  • Medium Grit Sandpaper (120-220): Used for refining the shape and removing scratches left by coarse grit sandpaper.
  • Fine Grit Sandpaper (320-600): Provides a smooth finish and prepares the surface for polishing.
  • Extra Fine Grit Sandpaper (800-1200): Used for final polishing and achieving a mirror-like finish.

Applications of Sandpaper in Jewelry Making

Shaping and Smoothing Metal

One of the primary uses of sandpaper in jewelry making is shaping and smoothing metal. Whether working with silver, gold, or other metals, sandpaper helps remove excess material and refine the shape of the piece. Coarse grit sandpaper is used initially to remove any rough edges or imperfections. As the jewelry maker progresses, they move on to finer grits to achieve a smoother finish.

For example, when creating a ring band, a jewelry maker may start with a coarse grit sandpaper to shape the metal into the desired form. They will then progress to medium grit sandpaper to refine the shape and remove any scratches left by the coarse grit. Finally, they will use fine grit sandpaper to achieve a smooth surface ready for polishing.

Preparing Gemstones for Setting

In jewelry making, gemstones are often set into metal settings to create stunning pieces. Before setting the gemstone, it is essential to prepare its surface to ensure a secure and visually appealing setting. Sandpaper plays a vital role in this preparation process.

When working with gemstones, jewelry makers use sandpaper to shape and smooth the edges of the stone. This ensures that the stone fits perfectly into the metal setting without any gaps or rough edges. The jewelry maker will start with a coarse grit sandpaper to remove any excess material and shape the stone. They will then progress to finer grits to achieve a smooth and polished surface.

Polishing Metal and Gemstones

Polishing is the final step in jewelry making, giving the piece its desired shine and luster. Sandpaper is used in conjunction with polishing compounds to achieve a high-quality finish. Fine grit sandpaper is used to prepare the surface for polishing by removing any scratches or imperfections.

For metal polishing, jewelry makers may use sandpaper in combination with a polishing wheel or cloth. The sandpaper helps remove any remaining scratches and prepares the metal for the final polishing stage. Similarly, when polishing gemstones, sandpaper is used to refine the surface and remove any blemishes before applying a polishing compound.

Choosing the Right Sandpaper

Choosing the right sandpaper for jewelry making is crucial to achieve the desired results. Factors to consider include the type of material being worked on, the desired finish, and the level of abrasion required. Here are some common types of sandpaper used in jewelry making:

  • Silicon Carbide Sandpaper: Ideal for shaping and smoothing metal surfaces.
  • Aluminum Oxide Sandpaper: Suitable for both metal and gemstone polishing.
  • Garnet Sandpaper: Often used for wood sanding but can also be used for metal and gemstone polishing.
  • Wet Dry Sandpaper: Designed to be used with water or lubricants, making it suitable for wet sanding and polishing.


Sandpaper plays a crucial role in jewelry making, allowing jewelry makers to shape, smooth, and polish metal and gemstones. From shaping metal to preparing gemstones for setting, sandpaper is an indispensable tool in the jewelry maker’s arsenal. By choosing the right grit size and type of sandpaper, jewelry makers can achieve the desired finish and create stunning pieces that captivate the eye. So, the next time you admire a beautifully crafted piece of jewelry, remember the crucial role that sandpaper played in its creation.
