The Eight Stars of a Round Brilliant Cut Diamond

The pattern of eight stars seen through the top of many round brilliant ideal cut diamonds is actually a reflection of the eight pavilion main facets that are found on the bottom or pavilion side of  the diamond...  The pattern of eight stars is not visible in all round brilliant cut diamonds because of variations in the crown and pavilion angles of the diamond.  Better cut ideal cut diamonds exhibit the pattern of eight stars and sometimes this pattern can be seen with the naked eye...  It's kind of cool!  The pattern of eight stars is more visible in larger diamonds simply because the viewing area is larger, the pattern of eight stars may be seen in smaller diamonds using magnification...  The pattern of eight stars may be seen easier using an instrument called a Gems Fantasy Scope which encompasses a small magnifying lens and a colored piece of filament paper that serves to diffuse the light and enhance the appearance of the pattern.  If you think this concept is cool, you should check out our Hearts & Arrows diamonds which exhibit not only a pattern of eight stars, but a symmetrical pattern of eight hearts as well...  Where do the hearts come from?  See that upside down kite shape facet in the middle of the top of the stone?  That's a bezel main and when viewed from the bottom of the stone through a Gems Fantasy Scope, certain diamonds cut to very precise proportions will exhibit the pattern of eight hearts...
