<div>This is a heavily modified version of Alexandre Wolkonsky's "Chevron Rectangle CC" that was made for a piece of rubellite shown in the photo. While that design does have angles listed for 1.10 L/Ws, it could be simplfied and retain performance by just offsetting the indices towards the long ends, similar to some girdle facets on diamonds where weight retention was a concern. This is a trick that can be used on a few designs to alter their L/W ratio slightly while still maintaining the same facet angles, provided they don't have facets on cardinal indices.<br />
