Original Capodimonte porcelain was produced in Naples, Italy between 1743 - 1759, then was revived between 1771 - 1806. These beautiful porcelain objects are rare and valued in the thousands of dollars.
In the 20th century, items marked Capodimonte were produced in Italy and feature a simple N with a simple stylized crown above it, in blue. There have been variations of marks over the years. That particular mark means the lamp was made between 1925 - 1967.
Twentieth-century decorative Capodimonte can appear quite old and ornate. They feature a variety of elements including romantic human figures, cherubs, flowers, scrolls, and gold highlights. The more valuable lamps have been reproduced but you can tell an authentic piece by looking for an artist's signature, though not all pieces have one. The best Capodimonte pieces come with a certificate of authenticity that includes a scroll design.
Although the public's interest in ornate, romantic design has faded over the years, a fine lamp in perfect condition can be worth hundreds of dollars. Rare, vintage lamps can fetch just above one thousand dollars. You can check the Capodimonte site and contact them for information on your particular lamp.
Capodimonte is still being produced today.
