Display organizers said thousands of people are expected to come daily to Prague Castle to view the valuable gems held in the castle's late-Gothic Vladislav Hall, the Czech press agency CTK reported Saturday.
In addition to marking this year's re-election of Czech President Vaclav Klaus, the exhibit represents the 90th anniversary of the founding of the Czechoslovak Republic.
The display, which will continue until April 29, includes royal jewelry dating back to the reign of Charles IV, the king of Bohemia who ruled between 1346 and 1378.
Prague Castle Administration head Ivo Velisek told the news agency that despite the value of the jewels, there was no reason to be concerned for their safety during the exhibition.
"The exhibition is thoroughly protected with the aid of the Castle Guard and the police," he told CTK.
