This design's crown is as close to a perfect Koch Snowflake (another simple fractal) as possible with a 96 index. The light return is a bit low, but it's a dome (which should help pale materials retain color, and will boost dispersion). Works in materials from beryl to rutile (RI = 1.58 - 2.62) with no changes, but I prefer aquamarine. Suggested width = 20-30 mm
