[0003] However, because the refractive index of the above-mentioned imitations, especially those made of glass or plastic, is lower than that of diamonds, it is difficult to satisfy the geometric conditions of total reflection, so the brilliance of such imitations cannot be compared with that of diamonds. real diamond

Embodiment Construction

[0029] Figure 1a to Figure 1d The gemstone 1 shown is made of glass and has a back face 2 that meets the point 3, wherein, as is usually the case with gemstones sold on the market with the Chaton designation, eight flats 4 emerge from the edge 9 (these form regular polygons) converge towards the tip 3. These planes 4 form the facets of the back 2 of the gemstone 1 . Instead of the edge 9 , an edge strip 10 can also be provided.

[0030] exist Figure 1b It can be seen in the side view of the gemstone 1 according to the invention that it has a faceted face 5, wherein eight planes 6 start obliquely from the edge 9 and end here in a regular octagonal Flat top surface 7 in. The front side 5 is provided with a specularly reflective surface 12 , the edges of the front side 5 being shown with dashed lines because they are located below this specularly reflective surface 12 , which is preferably designed as a reflective layer. The specularly reflective surface 12 itself is not sh...

Abstract

The invention relates to a jewellery stone with reflective front. Gemstone (1) having a back (2) tapering to a tip (3), and a front which is cut in a faceted manner (5), wherein regions opposing said tip (3) being mirrored (12).

Description

technical field [0001] The present invention relates to a gemstone having a back face meeting at a point and a faceted face. Background technique [0002] In order to obtain inexpensive alternatives to real diamonds, precious stones made of glass or plastic or also artificial stones such as zirconia have long been used. Here, gemstones made of glass or plastic as well as engineered stone have faceted surfaces so that the brilliance of a diamond can be mimicked as accurately as possible. [0003] However, because the refractive index of the above-mentioned imitations, especially those made of glass or plastic, is lower than that of diamonds, it is difficult to satisfy the geometric conditions of total reflection, so the brilliance of such imitations cannot be compared with that of diamonds. Gotta be a real diamond. [0004] In this case, such gemstones generally have a back converging towards the point, which is separated from the front by a so-called rondiste. The front s...
