Doorknob, or door jewelry?

Haute Déco's new line of doorknobs places an emphasis on ornamentation.

In fact, it's more "door jewelry" than "doorknob," riffing off Van Cleef & Arpels’ Alhambra jewelry collection.

Petals for Decorex also incorporates a four-leaf clover motif.

"One of nature’s simpler wonders, the four-leaf clover – or Quatrefoil -  represents Hope, Faith, Love and Luck," said the company in a statement. "It has been used throughout the ages, in Moorish and Middle Eastern architecture, in Byzantine churches, Middle-Age cathedrals and Venetian palaces. It was a much-loved motif of XIXth century Gothic revival, well-documented in pattern books such as the Grammar of Ornaments by architect Owen Jones."

"One of the best-loved motifs of contemporary luxury brands, it is constantly being re-interpreted in new contexts and applications, Haute Déco’s being one of the most innovative of recent times," the company added.
