The exact date of the Spoonmaker’s Diamond’s entry into the Ottoman Palace is unknown, but sources indicate it was incorporated into the treasury prior to the reign of Sultan Mahmud II (1808–1839). The diamond’s name derives from various legends surrounding its arrival in Ottoman lands; the most prevalent account holds that it was brought by a spoonmaker. The diamond was preserved as part of various imperial jewelry collections and acquired its current form during the reign of Sultan Mahmud II. During this period, its aesthetic and diplomatic value were both acknowledged. Throughout history, numerous sources have emphasized the diamond’s status as one of the symbolic treasures of the Ottoman treasury.

The Spoonmaker’s Diamond is exhibited in the Outer Treasury section of Topkapı Palace. This section is visited by an average of 15,000 visitors daily, and the diamond is among the most popular exhibits. Security at the palace is maintained at two levels: external security is managed by the Gendarmerie, while internal security is handled by personnel under the National Palaces Administration. All areas are monitored by 24/7 surveillance cameras, and mobile phone signals cannot penetrate the building due to lead-lined domes. These security measures ensure the protection of the Spoonmaker’s Diamond and render false the occasional claims circulating on social media that it has been stolen.
