Excellent quality copy of the highest military award of the Third Reich - "Oak Leaves with Swords and Diamonds in Gold" to the Knight's Degree of the Iron Cross. The size and appearance are completely consistent with the original. The copy is made of gilded brass, inlaid with faceted cubic zirconia. 
During all the years of World War II, this award was awarded to only one person - the pilot of the "Junkers", the Luftwaffe ace pilot Hans (in Soviet sources - Hans) Ulrich Rudel. 

In the original, the award is an additional fragment to the Knight's Cross in the form of oak leaves with crossed swords underneath them, made of high-grade gold and decorated with small diamonds. The size of the award is 25 x 20 mm, it is attached to the eye of the cross using an open wire ring soldered to the reverse. The award is essentially a piece of jewelry, made by hand (and probably in a single copy).

Until December 1944, the Knight's Cross of the Iron Cross with Oak Leaves, Swords and Diamonds was the highest class of the order. To receive this award, it was necessary to already have the junior class of the order, with oak leaves and swords, and again perform an outstanding heroic deed, or accumulate a total of achievements, which were points for air victories and the destruction of ground targets for Luftwaffe pilots, or the total tonnage of sunken enemy ships for the Kriegsmarine (for example, submariner Wolfgang Lüth was among those awarded). In the Wehrmacht and the SS, the main criterion for awarding the Knight's Cross (and, later, additions to it in the form of oak leaves) was the demonstration of outstanding personal courage. For generals commanding troops, a successful military operation could serve as a prerequisite for the award (for example, General of the Panzer Troops Hermann Balck and SS-Obergruppenführer Herbert Otto Gille, as well as Field Marshal of the Luftwaffe Albert Kesselring, commander of troops in North Africa Erwin Rommel, were awarded this honor). After the attack on the Soviet Union and the fierce large-scale battles on the Eastern Front, the greatest number of awards went to pilots, despite the fact that the scoring system was soon revised. Famous German aces who became holders of this award include Adolf Galland, Gordon McGollob, Hermann Graf, Helmut Lent, Hans-Joachim Marseille, Werner Mölders, Walter Novotny, Erich Hartmann, and also Hans-Ulrich Rudel). During the Second World War, only 27 people were awarded the Knight's Cross with Oak Leaves, Swords and Diamonds, and over time, there was a need to create an even higher degree of the award. As a result, on December 29, 1944, Adolf Hitler instituted its highest degree, the Knight's Cross of the Iron Cross with Golden Oak Leaves, Swords and Diamonds. In fact, only one person was awarded this award during the war: in January 1945, it was awarded to Hans-Ulrich Rudel, a super ace who became the most successful pilot of the Junkers Ju-87 dive bomber, who by that time had all the degrees of the Iron Cross. Only Hermann Goering surpassed him in the number of awards, but he did not deserve the Golden Oak Leaves with Swords and Diamonds.
