How Can I Identify the Factory Mark "N" on Porcelain Made in Italy?

The "N" symbol, appearing in blue under a coronet, can represent genuine Neapolitan Capodimonte porcelain originally made in a factory founded by King Ferdinand of Naples, which manufactured tableware and other decorative pieces from about 1771 through the early 1800s. The Capodimonte symbol is one of the most copied in pottery history, used from that time on to mark pottery ranging from genuine porcelain to fake earthenware or resin ceramics. Capodimonte was originally "capo di monte," meaning "top of the mountain" in Italian

To separate genuine Capodimonte porcelain from fake, a collector must know the genuine pottery marks, what they look like and when they were used by the factories manufacturing genuine porcelain. Most original Neapolitan Capodimonte porcelain is in museums or available only from high-end antique shows.

After the Royal factory closed, the Ginori factory in Doccia, Italy, purchased the mark, continuing to use a variation of the ?crown and N? to mark genuine Capodimonte pottery prized for its high quality. Later makers stole the symbol, manufacturing pottery of differing quality under marks similar to the original. Numerous companies use stickers as well as marking the pottery itself, which can help collectors identify collectible pieces. Capodimonte pottery remains highly popular and is manufactured in varying quality by multiple companies in styles including bas-relief flowers, vases and figurines.
