Abstract: A jewelry article optionally with one or more gemstones, includes one or more hollow core segments with at least one bore in a side wall, and optionally an element interconnected with the one or more of the segments formed by a flexible linkage. A segment may include a setting with rods to receive a gemstone. The segment(s), and optionally the element, are preferably in an annular array to form a ring, necklace and the like and may be of the same or different configurations. The segments also may have different arcuate circumferential lengths and cross sectional shapes preferably frusto-conical and may comprise only a portion of an article such as a finger ring or necklace and the like periphery. The linkage is formed by a pin secured to one segment or element and which pin passes through the bore into the hollow core of the adjacent abutting segment. A coil compression spring is captured to the pin in the hollow core of a segment and urges the adjacent components together.

Abstract: The present invention utilizes a computer program to size and orient one or more feature items on a jewelry design having a feature path. Typically feature paths are necklines, wristbands, broaches or rings. A feature item is a gemstone, set of gemstones or metal designs such as a cross, circle or other artful shape. The program and computer system of the present invention selects a feature path, detects a starting location on the feature path and then orients a first feature item in three dimensions on this feature path with respect to a three dimensional surface representing the jewelry wearer. Orienting the feature item in three dimensions is critical so that the feature item is properly displayed on the jewelry when the jewelry is worm. Once the initial feature item has been oriented, subsequent feature items are automatically placed on the feature path, sized with respect to the initial feature item and oriented with respect to both the initial feature item and the three dimensional surface.

Abstract: A platinum alloy has a white finish and comprises platinum, rhodium and ruthenium, with the platinum being present at a concentration of about 95% by weight, the rhodium being present at a concentration from about 2.5% to about 3.5% by weight, with increasing whiteness and workability at 3.5% Rh, and the ruthenium being present at a concentration correspondingly from about 1.5% to about 2.5% by weight, with the preferred composition being at about 1.5% by weight. In addition, methods of preparing the alloy and aesthetic items made with the alloy are included.
