Abstract

Jewelry setting with concave reflector (2) under the gems (1), precious stones (1), semiprecious (1) and glass (1) and larger perimeter than these, to be introduced by reflection, in the lower part of the "stone" (stock or pavilion (16)), a greater amount of light, coming directly from the outside, as well as the one that, having penetrated the "stone" by its upper part (crown) (15), escapes from it by the bottom (stock) (16), thus increasing its brightness considerably.

Description

JEWELRY CRIMPING WITH CONCAVE REFLECTOR UNDER THE GEM

The present invention relates to a concave reflector jewelry setting or setting system, which is placed under one or more precious, semi-precious or glass stones, usually transparent and faceted, with the aim of increasing their brightness. It comprises a concave reflector, smooth or faceted, which, being larger than the stone in its plan projection, causes both the light that enters the stone through the "crown" and then leaves it through the "butt", As the part of the light that comes directly from the outside through the area between the stone and the reflector, they bounce towards the inside of the stone through its lower part (stock), and go out again through the upper part of the stone (crown), which achieves a much more intense shine effect on the stone. The "stones" to which reference will continually be made in this writing, are crystallized gems or minerals, natural or synthetic, transparent and faceted, which are usually used in jewelry, including those known as "precious stones", semi-precious "and glass .

FIELD OF THE INVENTION

The present invention refers to the placement in jewelry settings, under the "stones", of a concave reflector of greater perimeter than these, whose function is to reintroduce the light into the "stone" through both the "butt" that escapes from it and bounces off the reflector, like the one that reaches the reflector directly without previously going through the stone. This reintroduction of light through the butt so that it exits the crown again after passing through the stone, increasing its appearance of "shine" and size.

BACKGROUND OF THE INVENTION

In the traditional nailing or setting of "stones" in jewelery, these are fixed to the structure of the jewel, supporting this part of the butt and fastened by tubular "claws", balls, staples, or burrs, among other means, to the fillet , to avoid displacement. In general, the lower part of the "stone" (lower part of the cylinder head) is usually left without metal, in order to clean it.

The light that penetrates through the crown of the "stone", through the phenomenon of refraction,

changes direction when entering

she and much of that light does not penetrate the

"stone", but, being reflected by the inclined lower facets of the cylinder head,

5

it comes out through the crown again, being visualized and producing the known phenomenon

as "shine".

The technique has developed models that optimize for each material the

ideal angles to keep most of the light from escaping through the stock,

since the light that escapes from the stock does not contribute to the brightness of the "stone", leaving

absorbed by other parts of the jewel or the wearer's own skin.

Many designs have been created in which

side openings with

in order to capture more light from the outside,

and even ways

reflectors

convex with this same purpose, but not there is a history of

placement of a specific concave reflector to channel part of the "lost" light, and

fifteen

even capturing, having a greater surface area than "stone", a greater amount of light

and project it into the cylinder head.

DESCRIPTION OF THE INVENTION

The invention comprises the placement of a concave reflector, smooth or faceted, under the "stone", which projects a large part of the light that escapes from the "stone" or that comes directly from the outside, causing the effect of greater brightness and a halo of light in the crown between the fillet and the perimeter of the reflector. This reflector can be a separate piece added and attached to the structure of the

25 jewel, or it can be made by creating such a concave shape in the jewel structure itself. This reflector can have any shape; and the shape can be different in its contour, allowing light to enter the stone butt. It can be made up of small flat or curved surfaces, which together define a global concave surface. You can exercise your function for the entire volume of the

30 stone, or only for a part of it, as would be the case with a reflective medium, which would produce special effects of intensity on the brightness of the stone. A reflector can perform its function for several grouped stones. The "stone" is held or nailed by "staples", or "balls", or any other

system, along the fillet.

DESCRIPTION OF THE OPTICAL PHENOMENA THAT ARE OBTAINED WITH THE REFLECTOR AND EXPLANATORY DRAWINGS Fig.A Plan diagram and elevation of the reflector. The "stone" (1) is nailed by means of claws, legs or balls (5) to the structure of the jewel. Under the "stone" (1) there is a concave reflector, which could be smooth (2), faceted (3) or mixed (2 and 3). The part of the stone called "crown" (11) and the "butt" (12) are indicated in the drawing. Fig.B Schematic section of the path of three "type" rays of light, coming from the outside: In the upper figure (B1) outlines the path of a ray of light (8) that, coming from outside, penetrates the area between the crown of the "stone"

(one)

And the perimeter of the reflector (2), supported in a generic structure of the jewel (6), more extensive. This ray is reflected consecutively in the reflector (2), leaving this same space between the perimeter of the reflector and the "stone", creating a luminous halo effect that makes the "stone" appear larger than it actually has. . In figure (82) the beam (9) is schematized which, penetrating through the area between the "stone" (1) and the surface of the reflector (2) supported by the generic structure of the jewel (6), affects an angle that introduces it inside the butt of the "stone", being able to be refracted and emitted to the outside by the crown. Increases the shine effect of the "stone". In figure (B3) the ray (10b) enters through the crown of the "stone" (1) coming from the outside, is refracted inside and falls on the inside of one of the facets of the cylinder head, at an angle lower than the "limit angle", so it escapes through the "butt". This ray bounces off the reflector (2) and is projected back into the "stone"

(one)

with the trajectory defined in the drawing (11). The case is also indicated in which the beam (10a) strikes the stone (1) in such a way that it does not penetrate it again but strikes the reflector (2) and leaves with a path (12) included between the reflector (2) and the stone (1). Fig.C Outlines of some of the different shapes are drawn, in plan, that the reflector may have, to adapt it to the artistic needs of the creation of the jewel or to the shape of the "stone". Figure C1 outlines an "oval" stone shape (1) with an oval shaped reflector (2).

Figure C2 outlines a "trillion" shaped stone (1) and a reflector

(2) composed of three joined spherical triangles.

5 Figure C3 outlines the tapered stone shape (1) "marquisse", and a reflector (2) composed of two concave surfaces joined. In figure C4 the reflector (2) with its generic support (6) with lateral opening (7) is schematized in elevation. The upper parts of the reflector perimeter allow to fasten the "claws" (3) for nailing the "stone".
