摘要： An oval-cut diamond comprises a girdle having a contour line in an oval or oval-like shape, a crown above the girdle having an octagonal table facet on a top of it and a pavilion below the girdle. That is a modified oval brilliant cut diamond, in which one of the crown and the pavilion is rotated by about a sixteenth revolution around its central axis from an ordinary brilliant cut diamond. The girdle is of a ratio (b/a) of a short radius to a long radius of 0.6 or more, in which a radius in long axis direction is "a", and a radius in short axis direction is "b". A pair of pavilion main facets positioned opposite to each other with respect to the central axis has a pair of crown main facets or star facets facing the pair of pavilion main facets through the girdle. The two pavilion main facets, the two crown main facets or star facets and the table facet have a common vertical plane within the facets so that brilliancy of reflection lights coming out of the table facet and crown facets is enhanced.

摘要： When a diamond is brazed to a metal substrate, while obtaining a stable joining strength, a joined interface of the diamond is not eroded to provide a good joint with a beautiful view. A brazing-filler material containing at least one selected from a group consisting of gold and silver, and copper as principal components, and further containing 0.001 to 5 mass % of vanadium is used. Preferably, a vanadium content is not more than 2.0 mass %, and more preferably not more than 0.5 mass %. Using this brazing-filler material, unidirectional solidification is performed from a side of diamond to form vanadium carbide in a joined interface in a shape of islands, and thereby an interface having a beautiful view with stable joining strength can be obtained. In addition, strong joining is possible also by a usual solidification method.

摘要： An oval cut diamond having a girdle with elliptical or nearly elliptical outline, a crown which is above the girdle and has an octagonal table facet in the top section, and a pavilion which is below the girdle. The girdle has an aspect ratio (b/a) of 0.6 or more where a is the radius in the direction of the long axis and b is the radius in the direction of the short axis. A pair of pavilion main facets arranged opposite to each other with respect to the central axis have a crown main facet pair or a star facet pair respectively facing them across the girdle. Since these two pavilion main facets, two crown main facets or star facets, and the table facet have a common vertical plane in their facets, brightness of reflected light emerging above the table facet and the crown facets is enhanced.

摘要： An ornamental diamond is provided as an extremely bright diamond with numerous reflection patterns when viewed from above its table facet and crown facets. The diamond has the same crown as the round brilliant cut and its pavilion consists of a first pavilion and a second pavilion separated by a horizontal division plane. Lower girdle facets and pavilion main facets are bent by the horizontal division plane between the first and second pavilions, and a first pavilion angle is larger than a second pavilion angle. The ornamental diamond having the two-stage pavilion is much more brilliant than and has twice as many reflection patterns as the conventional round brilliant cut.
