| * |  | "Crowning" Jewel or "Crown"
     Jewel? 
 The
     Leadership Course
     is the crowning jewel of
     Werner's work of
      transformation.
     And yes, I do
     mean
     "crowning" jewel, not "crown" jewel.
 
 Saying "crown" deploys a noun, a static object, a thing.
     Saying "crown-ing"  deploys a verb (an
     inflected  verb actually), a
     present
     participle, a gerund to be exact. There's process  in
     it, something's
     happening,
     it's ongoing.
 
 So "The
     Leadership Course
     is the crowning jewel of
     Werner's work of
      transformation",
     not "The
     Leadership Course
     is the crown jewel of
     Werner's work of
      transformation"
     which is ubiquitous, milquetoast,
     simply
     not as
     powerful.
