A ‘decagon’ as you can see, has ten pavilion mains, not eight like a traditional modern round brilliant. Also, it has 10 straight edges, not a circular perimeter. Having 10 pavilion mains will result in many more, smaller, light slivers versus the stones with 8 pavilion mains, which, depending on their size, can be smaller or larger slivers of light, but still larger than those on the 10. Different flavors. Like vanilla and chocolate. Neither is bad, its what you prefer.
