The present invention provides one or more head sections having a setting that are releasably engaged with one or more bases.

The invention involves a modular jewelry system and method for constructing a modular jewelry system. The system includes a base having a bore, the side wall of the bore including a groove having a slight helix. The helix includes a small protrusion beyond which the helix flattens and the slot ends. A charm, stone or the like, has an outwardly extending stem; the stem including at least one outwardly extending tab. The tab is sized to cooperate with the groove, so that the stem is pulled into the bore as the stem is rotated until passing the protrusion, whereby the stem is locked into position in the bore.

A round stone is intended for being inserted contiguously with other similar stones to as to conceal the setting of the stones. Facets are bevel-formed between the girdle and the pavilion. Grooves, open at the two ends thereof, are formed, as by sawing in a plane perpendicular to the axis, in the facets to receive the setting claws.

Systems that are used to support a plurality of frames arranged in a specific configuration are contemplated. The system comprises outer frame panels that removably couple to the plurality of frames. It is contemplated that the outer frame panels collectively couple to the plurality of frames to thereby provide additional stability to maintain the plurality of frames in the specific configuration, such that the risk of the plurality of frames losing their specific configuration during transport is reduced.

A method and apparatus detects an unknown deposit in soil of a known mineral or gemstone using characteristic scents of the mineral or gemstone. The method may disturb the soil, for example, by causing a chemical reaction in at least part of the soil such that a mineral or gemstone present in the soil emits a characteristic scent. The unknown deposit of the known mineral or gemstone can be detected in real-time or near real-time in the field.

An improved jewelry ring sizing mandrel and method of use thereof for sizing of an improved anatomically correct jewelry ring, with the mandrel having a tapered elongated body, elongated pairs of opposing outward extending portions and being spaced apart from an adjacent outward extending portion with each pair of opposing outward extending portions defining an outer width, and pairs of opposing elongated recess cavities with one of each of the pair of opposing elongated recess cavities positioned between each adjacent opposing outward extending portions and defining a cavity depth that is less than either of the adjacent opposing outward extending portions with each pair of opposing recess cavities defining a cavity width and the recess cavity width of the pair of opposing recess cavities being less than the outer width defined by any pair of adjacent opposing outward extending portions.

The invention relates to an article of jewelry comprising a transparent wall which forms a housing provided to receive a precious or semi-precious stone which is immersed and movable in a substantially transparent liquid in the housing and at least one piece which is movable in the liquid and which has the same refractive index as the liquid, the piece immersed in the liquid being substantially optically indiscernible. The housing is delimited by two walls the internal faces of which are preferably mutually parallel, and the stone is inserted into the piece in order to form a movable decorative element, the piece immersed in the liquid being substantially optically indiscernible and comprising an axis of revolution and two guiding surfaces which are adjacent to the internal faces, respectively, and which allow the movable decorative element to move freely in terms of translation and rotation in the liquid about the axis of revolution inside the housing.
