A mounting holds a grooved gemstone invisibly to a setting. One end of the mounting has arms or extensions to receive the gemstone and protrusions extending inwardly from the arms to fit in the grooves of the gemstone, the mounting further comprising a holding configuration for holding the mounting to the setting. Insertion of the mounting into the setting may in one version distort the holding configuration and levers the arms to press harder into the groove.

An earring for a pierced ear includes an ornamental member and an earring post. The earring post includes a base, a first prong and a second prong. The earring post is made of a deformable metal so that the first prong and the second prong can be bent to secure the earring in an ear without requiring detachable pieces.

The present invention relates to a decorative piece comprising a support produced in a material which does not include plastic deformation and in which at least one hollow is provided, characterised in that said hollow being filled with a first material being an at least partially amorphous alloy forming a substrate in which at least one housing is provided, said at least one housing being designed so that at least one aesthetic element can be housed therein.

The invention relates to a decorative piece comprising a plurality of stones and a device for fixing the stones relative to each other, the fixing device comprises a single base made of a first material which makes it possible to attach all the stones relative to each other by one of their faces, the kites of stones are mounted edge to edge relative to each other so that said single base is masked, characterised in that the first material is an at least partially amorphous alloy. The invention likewise relates to the method for manufacturing such a piece. The invention relates to the field of jewellery, gemstone articles or timepieces.

A gemstone positioning fixture, including a base and a cover plate applied over the base. The cover plate has apertures, one for each gem to be worked on. At least one biasing member is positioned beneath the plate. The biasing member applies an upward force to the gems to contact the cover plate. The plate is formed of materials that conduct electricity, so as to conduct any charged particles away from the gem work surface.
