Designed by Marco Voltolini, Morning glory is a magnificent, high-facet-count round faceting design that produces an extraordinary flower-burst pattern of light and reflection.
Calculated for Quartz (R.I. = 1.540) and working brilliantly on higher refractive index gemstones, this complex 151-facet design utilizes 5-fold mirror-image symmetry on an 80-index gear to create a rounded, highly reflective gemstone.

|---|---|---|---|
| A | 30.00° | 06-10-22-26-38-42-54-58-70-74 | Set girdle thickness |
| B | 15.00° | 06-10-22-26-38-42-54-58-70-74 | No meetpoints (stop before meeting girdle) |
| C | 13.06° | 80-16-32-48-64 | Cut to meet A (pay attention...) |
| D | 0.00° | Table | No meets |
Suitable Gemstone Materials
Due to its high facet density, Morning glory creates amazing scintillation in light to medium-colored roughs:
- Quartz Group (RI 1.54): Citrine, Lemon Quartz, Amethyst, and Clear Quartz.
- Beryl & Topaz (RI 1.57 - 1.62): Aquamarine, Morganite, and White Topaz.
- Higher RI Gems: Tourmaline and Sapphire for maximum optical fire.
