Centro Collection / 100 facets

[GreenBling]

Tried on a few Centro pieces today. They are all 100-facet cuts. Very very sparkly. The pave designs are absolutely stunning with the blinding blings. However, I don't care for the bigger stones. There's a dark flowery pattern under the table. It looks like a hollow from a distance. The sales lady says its a beautiful flower but it looks more like leakage in flower shape. It's apparent even in 0.15 stones. Is it supposed to be like this? Can they cut 100 facets without leaving a dark flower?
