Instructions
Lay your 4-by-4-inch acrylic flat and drill a 1/4-inch deep 1/4-inch hole near each corner so the centers of the holes are each 1 inch away from the edges.
Glue the 1-inch rods into a pair of the holes that are 2 inches apart. Do not glue them so they are catty-corner.
Glue the 1/2-inch rods into the last pair of holes. Let the glue dry according to the instructions listed on the package.
Set your crystal or other special stone on the mount so it rests on the 1-inch rods and is held back by the 1/2-inch rods.
