Abstract: A pierced earring holding and locking system is provided that securely retains the locking system in both locked and unlocked configurations by providing an engagement mechanism in the body of the locking system, such as a spring or interlocking surface projections and depressions. The body of the locking system may include a shaft, arms extending from the shaft, and a recess formed between the arms. A locking bar is pivotally engaged with the body section and movable between a first position with the locking bar substantially parallel to the shaft, and a second position with the locking bar substantially perpendicular to the shaft. The body section further may include a spring biased towards the locking bar, the spring being compressed by the locking bar when the locking bar is in the first position.

Abstract: A pair of extensions for a gauge for measuring objects is disclosed. Various construction details are developed that provide extensions that may be used to determine the size of objects, such as gemstones, that are embedded within a structure and not accessible by conventional gauges. In a particular embodiment, a pair of extensions each having a sleeve and a member extending outward from the sleeve. The sleeve fits over a finger of the arms of a gauge and includes a set screw to attach the sleeve to the finger. The members include contact surfaces to be placed in contact the object to be measured. In another particular embodiment, at least one of the extensions has a tapered cross-section such that the distal end of the cross-section is sized to be inserted within the structure surrounding the object to be measured.

Abstract: A jewelry display and information device is disclosed. The device includes an insert that may be folded about an item of jewelry to securely retain the item. The device further includes an outer surface for displaying information about the item of jewelry. After folding, the insert may be slid into a pocket in a transparent sheet for display of the item of jewelry and information about the item.

Abstract: By providing a slender, elongated shaft having the terminating end portion of the shaft pivotally engaged with the main shaft, a unique, one-piece, pierced earring holding system is achieved. The pierced earring holding system of this invention is usable with any desired pierced earring design, and assures secure and easy attachment to the pierced ears of the user, while also completely eliminating potential loss of the earring.
