First measure your gemstone. My oval gemstone measures 20 x 15mm.
Looking at the 20 x 15 mm line on the Gem Board or the chart above, you can find the length that the wire should be and where the bindings should go indicated by the little marks.
Note: Practice wire 22 gauge wire is thinner than the 20 gauge wire.
First using practice wire to measure the wire for the size of your gemstone. Using the markings on the Gem Bead Board or the chart, mark your wire with a felt tip for the proper length.
For my gemstone I'm using the marks below the 20 x 15 mm graph line to note where to put my bindings.
If you are looking at a clock the Gemstone bindings are usually put at the 2 o’clock, 4 o’clock,
8 o’clock and 10 o’clock positions.
If you do not have the Advanced Gem Bead Board, I have supplied you the equations and lengths on the chart.
Next hold the measured wire with the marking at the “0“ on the scale on the Gem Bead Board or on a ruler.
Then measure 4 to 6 inches more which allows you 2 to 3 inches on each side of your Cabochon or Gemstone for your pretty work.
You will normally cut a total of 4 pieces of 20 gauge practice wire 6 3/4 inches long.
4” + 2 3/4” = 6 3/4” and for your prongs a 22 gauge practice wire 7 ¾ inches long.
Notice the groove on the Gem Bead Board Scale, it is handy for holding beads, or cutting wire. The cutters fit in the groove nicely.
