Oval and Marquise Gemstone Faceting
Cutting oval and marquise shaped gems is only moderately difficult if you have a preforming device and an accurate means of aligning it, and then the preform, with the lap. Measuring with a scale from the lap to a point on the preformer while it is in one index setting, then rotating it 180o and then measuring again, the adjusting and trying again and again until the two measurements are equal, seldom gives a sufficiently accurate result. You must have a accurate and stable tool to make your measurements with and you can make one in a few minutes to create stunning gemstones that can be used in making handmade jewelry.
