Fortnite Item Shop cosmetics come in many shapes and sizes. Depending on the category to which they belong, players can expect to see a wide variety of cosmetic items that range from wacky to outright marvelous. Given that many players are part of the metaverse, there's something for everyone. However, not all cosmetic items last forever.While they are the lifeblood of the game, many are vaulted and become rare. Those fortunate enough to own them are considered extremely lucky. Although they can't be traded, they can be shown off in-game - which is what most players tend to do. That being said, here are 10 Fortnite Item Shop cosmetics that are as rare as diamonds.Note: The rarity of the cosmetic items has been based on when they appeared last in the Item Shop.Rust Bucket and nine other Fortnite Item Shop cosmetics that are rare as diamonds1) Rust BucketChewy@ChewyThompsonnNew free Rust Bucket black bling in Fortnite! pic.twitter.com/x3oygH7m6R71New free Rust Bucket black bling in Fortnite! pic.twitter.com/x3oygH7m6RWhen it comes to rare cosmetic items in Fortnite, Rust Bucket (Back Bling) is at the very top of the list. It was last listed in the Item Shop 1,922 days ago. While this may sound strange, there's a valid reason behind this. This cosmetic item was given out as a freebie due to server issues in Chapter 1 Season 3. Since it was exclusive in a manner of speaking, it was vaulted after a few days.2) FreshPlay Central@PlayCentralGG#Fortnite Keep those moves fresh.The new Clean Groove Emote is available now! pic.twitter.com/2OHydkecP32#Fortnite Keep those moves fresh.The new Clean Groove Emote is available now! pic.twitter.com/2OHydkecP3Fresh (Emote) is based on the Carlton dance by Alfonso Ribeiro and is the most sought-after Emote in-game.

It was last seen 1,619 days ago.6) ReflexFortnite News@FortniteBRReflex is now the rarest shop Outfit, last seen 1,515 days ago. #Fortnite pic.twitter.com/VRQEJTmN884540180Reflex is now the rarest shop Outfit, last seen 1,515 days ago. #Fortnite pic.twitter.com/VRQEJTmN88Reflex (Outfit) has not been seen in the Item Shop for 1,603 days. Given that it's a completely normal cosmetic item, it seems rather odd. But there's a good reason behind it. The Outfit in question was part of a collaboration with Nvidia. Such being the case, the cosmetic item was not kept in the Item Shop for long. After just two appearances, it was vaulted.7) RoadtripFortniteSweat@FortniteSweat19Season Shop (Season 1) - Glider | Fortnite: Battle RoyaleIt is an Uncommon (Green) Glider that you could find in the Season Shop of Season 1!
