You got snowed if someone got you to believe this. Sparkle is simply light being reflected to the site lines. More facets do not equate to more sparkle. What creates the best sparkle is an ideal cut. You can have facets out the ying-yang, but if the table is a thin cut then the damned thing anin't gonna sparkle to anything but her finger. It's simple geometry. Thinner cuts allow light to almost pass directly through the stone. Thicker cuts do the opposit - the reflect light to the outer walls. And ideal cut will reflect light directly at the same angle it came in, thus hitting the opposite side and shooting back up toward the sight lines.
