Regal themes and notions of nobility have been used in nearly every industry, from pop culture fiends who worship real-life royalty like Prince William to designers who long to channel the elegance and rich history of kings and queens.
Implications - Royalty has the ability to inspire many trends. Examples of this are easily seen today with the nuptials of William and Kate, whose engagement ring has inspired a trend of sapphire centres in the jewelry industry. The reason why is that royalty carries an elegance and power most want to emulate in their daily lives. People want to be seen as high class versus their normal social standing.
