This is a long trilliant that was the result of experimenting with biasing indices to produce different L/Ws. The single set of pavilion tiers should make this forgiving to cut, and it is intended for quartz tips with a single large facet and offcuts too triangular to fit a pear. Cuts in RIs 1.54-2.14 with no changes.
