If "Patterned Static Scintillation" involves the observance of diamonds in a still (static) position, "dynamic scintillation" simply involves observance during movement of either

• the diamond
• the observer
• the light source or
• all of the above

Under the definition where GIA talks about this patterning, the bright and dark areas still exist even when the diamond is tilted, however the patterning is obviously different.  Excellent scintillation no matter the view.  Rocking and tilting the diamond involve movement which changes our definition from static to dynamic.

Same diamond in face up view (left) and tilted (right). Excellent contrast of bright and dark areas in either view.

I refer again to our checkerboards.

Patterned Dynamic Scintillation

Other innovative cutting factories have taken the art of patterning to new levels and have introduced patterned diamonds that break away from traditional cutting, producing an appearance that is not only different but which many find very appealing.  Below are the 81 faceted Eighternity Diamond and the 91 faceted Solasfera diamond alongside one of many flavors of H&A. Each exhibits beautiful optical symmetry and light return, what is most beautiful is left for you to determine.

You may be wondering... which more accurately depicts the diamonds appearance?  You may be surprised to learn that it is the model!  Our photographic setup depicting contrast (brightness and static scintillation) and emphasizes features about contrast within diamond that we purposely attempt to capture in our photography. The arrows and other dark areas do not appear as dark to the human eye but are more similar to our customized modeled images in those conditions.
