How to make Faceted gems using plexiglass

Materials

• 1/4" thick Plexiglass or thicker (glass stores sale scraps really cheap)
• Transparent glass paint. Lefranc & Bourgeois Glass & Tile makes the most clean glass paint I‘ve ever used. I highly recommend it.
• Krylon Silver Leafing Pen or tin foil

Tools

• ax base glass marking pencil, Stabilo makes a good one call Satbilo All Dremel tool
• A stationary scroll saw or a dremel cutting disk
• Grinding stone
• A flat metal file “Mill Bastard” with parallel groves/teeth
• buffing wheel and polishing compound

Note: all of these tools beside the scroll saw and file comes with the Dremel Kit

Procedure

Draw the base shape on the Plexiglas use a your wax pencil if it was covered in plastic scratch resist sheet. If not you can draw directly onto the paper cover.

Using either the scroll saw or cutting disk cut the shape out. If the plexiglas was cover in the plastic remover it before cutting, the plastic sheet will melt into the plexiglas.

For the cutting disk cut outside the shape since it also can metal the Plexiglas.

Using a grinding stone remove any cutting imperfections and reshape as needed.

Using your file take off the corners to create the facets.

When all your shaping is done and is relatively smooth use the buffing wheel and polishing compound make the plexiglas clear again.

With the finish stone paint a thin layer of glass paint on the back of stone. After 2 to 3 hours it will be dry. Note if you don’t like the thickness of the paint or have air bubbles, with the L&B glass paint you can soak the stone in water and peal the paint off.

For the setting glue in tin foil into where the gem will sit or simply brush in the leafing pen into where you want it.

The finished pieces

My necklaces here has a flat back since I didn’t want it protruding to far out. You can make facets on the back as well but I recommended you find Plexiglas sheet thicker then ¼” since you want the back side to have deeper angles on it. If you find ½” thick plexiglas you can shape a diamond from it.
