Set gemstones, gemstone settings, and methods of setting gemstones including a cut gemstone having a girdle a plurality of horizontal grooves each having an upper edge and a lower edge, wherein the upper edges of the plurality of horizontal grooves are located within the girdle, abut a lower edge of the girdle, or are within 1 millimeter beneath the lower edge of the girdle, and a cylindrical barrel having a central aperture, an open top, a rim at the top forming an upper edge of the barrel, and a plurality of flanges projecting into the central aperture of the barrel located directly beneath the rim, wherein the flanges project into the grooves to maintain the gemstone within the barrel.

A method for manufacturing ornaments made of precious metals is provided. A sheet, plate or foil made of pure precious metal—i.e. having a fineness equal to or greater than 999 parts per thousand—is provided, a profile of a desired shape is traced, and the sheet or plate is cut according to the profile to obtain an ornament having the desired shape. The method obtains ornaments made of precious metal of any two-dimensional shape in a short time with limited manufacturing costs. The method can be used to produce a large number of variants of commercial collections of jewels and/or ornaments made of pure precious metals according to the commercial choices of the manufacturer, and to obtain “tailor-made” ornaments made of pure precious metal—i.e. starting from a specific design of the user—in a very short time, or even immediately.

Disclosed is a timepiece component including at least one housing intended to receive at least one precious or non-precious stone and including at least one first end, referred to as the setting end, and a rail. The rail is located on the periphery of the housing, and is arranged to allow the stone or stones to be inserted into the rail at the first end of the housing, such that the stone or stones can slide in the rail along the longitudinal axis of the housing, and to hold the stone or stones once inserted into the rail in a direction perpendicular to the longitudinal axis of the housing.

A double ended hand tool created to pick up place and position flatback crystals, gems or other tiny items is disclosed. The tool contains a hollow, conical end which securely encases each crystal allowing the operator to easily position the crystal with no slip. The tool has a first end and a second end coupled by a shaft. The first end has a wax tip which allows the user to pick up crystals or other small items. The second end has a hollow narrow extended portion which allows the users to manipulate the crystal or other small items.

A method for producing a gemstone, in particular a diamond, in the shape of a star with several arms, the method including taking a basic, brilliant cut gemstone, the gemstone including a basic crown, a basic pavilion and a basic girdle joining the basic crown and the basic pavilion and defining a plane, cutting a plurality of facets in the respectively basic crown, pavilion and girdle, to obtain a transformed gemstone delimited by a periphery, laser cutting the periphery of the transformed gemstone to produce the star shape.

A size enhancing jewelry setting for a precious stone includes a setting body with a holding portion that is configured to engage and hold the precious stone affixed to the setting body. A faceted plate is supported by the setting body. The faceted plate has a central opening for the passage of a pavilion region of the precious stone therethrough, an upward facing reflecting surface that partially extends below a girdle of the precious stone and which faces a portion of the pavilion region of the precious stone in spaced relationship thereto, and a portion that protrudes peripherally beyond the girdle of the precious stone. The faceted plate is being configured to reflect light that emanates from the pavilion of the precious stone outwardly and upwardly, the reflected light surrounding and extending beyond the precious stone to produce a visual effect of the precious stone being larger in a peripheral dimension thereof than it actually is.
