Choosing the Stone and Jewelry Piece
When choosing the stone, consider color, chip size and price. Color is strictly an artistic consideration, and price a personal choice, but chip size will affect your finish piece artistically.
Chip sizes range from a fine powder to 1/2-inch pieces. Be sure your chip will fit into the recess, but also note that the size will affect the appearance of the final product. The smaller the pieces, the more even the color will be. Crushed stone in various colors and sizes can be found at many large craft stores, but can also be purchased online.
Filling the Inlay
To fill the inlay with the stone and resin, fill approximately 3/4 of the recess with the crushed stone. If you are working with a powder, you may find a small paint brush helpful in filling the recess.
When the stone is in place, mix your resin filler according to package directions, and be sure to use a clear epoxy resin.
For small spaces fill the epoxy in the recess with a craft stick or toothpick. Use the toothpick to pop any air bubbles that may form. The mixture of stone and epoxy should be filled just above the lip of the recess. Be careful here because while you want the resin to be just slightly past the top of the recess, you do not want it to spill any onto the jewelry piece.
Finish your stone inlay by sanding and polishing. For best results, use finer grades of sandpaper as you work. For example use a 220 grit sandpaper to sand down to within a millimeter of the top of the recess. Then switch to a much finer 400 grit sandpaper and sand all the way down to the lip of the jewelry. The jewelry piece itself should be free of resin at this point. Now you can polish the resin over your inlay to create your finished piece.
