A Pin Wheel in Rose Quartz
Remember those pin wheel toys we played with as children? I wanted to design a cut that looks and flashes just like one. So, I came up with this. It’s easier than it looks.
The quartz I used for this example has a nice color, but it’s a little on the silky side. As a result, the photos look a little fuzzy. However, the silk did cause some interesting color and dispersion when I photographed the stone. The blades of the “pin wheel” show pretty well.
If you cut this in a gem material with a lower refractive index (like quartz), the blade pattern tends to appear more pronounced.
Enjoy cutting your own Pin Wheel.
