The Silver Crown (Dutch: Zilveren Kroon) was a crown made in 1502 for the coronation of Leuvis II. This crown was the symbol of the Royal Family and is presently used on the Greater Arms and the Royal Standard.
This crown was last used to crown Willem II in 1649. During the Civil War, the crown was lost and subsequent kings were crowned without it. The government issued a reward of 40 thalers in silver, which is still redeemable if one finds the crown and returns it.
The Indian Diamant (Dutch: Indische Diamant) is one of the largest cut diamonds in the world, weighing 118.6 carats (25.12 g).
