"Ah, but the Third Hallows is true Cloak of Invisibility ... I mean to say, it is not a traveling cloak imbued with a Disillusionment Charm, or carrying a Bedazzling Hex or else woven from Demiguise hair, which will hide one initially but fade with the years until it turns opaque. We are talking about a cloak that really and truly renders the wearer completely invisible ..."
-- Xenophilius Lovegood (DH21)
Presumably causes the target object to bedazzle any observer.
References from the canon
- Xenophilius Lovegood said that a travelling cloak may be imbued with a Bedazzling Hex in order to make it function as an Invisibility Cloak (DH21).

There may be a sly undertone of humor in Mr. Lovegood's remark about bedazzling an ordinary cloak to make it invisible. In the Muggle world, to "bedazzle" can mean to embellish clothing with rows of rhinestones or fake gems - and those certainly don't make clothing less visible!
