This design is Tom Herbst's TearBuncle with a modification requested by Nick Fabri (NickAtNight - Gemology Online Forum). The design has been optimised for RI 1.76 and works well in light to medium saturated garnet and sapphire. Nick has named this variation of Tom's design after his grandsons recovery from recent open heart surgery.
