Definitions
- the present invention relates to a cut gem consisting of diamond or a stone comprising at least one axis of crystallographic symmetry ternary and a refractive index and a dispersion substantially equal to those of the diamond, comprising a first predetermined number of facets cut in the crown and a second predetermined number of facets cut in the cylinder head around a central geometric axis of symmetry, said facets of the crown and the cylinder head are arranged around said central geometric axis of symmetry in a substantially hexagonal arrangement.
- GB-A-1.015.389 we reveal gems with a size resembling flowers with eight or sixteen petals of convex shape circular arranged around a central geometric axis.
- the outer contour can be straight, pointed or sinusoidal.
- US-D-384,592 illustrates diamond cuts with a flower shape with four petals with rounded outer outline separated by a point-like trough.
- the object of the present invention is to create a gem of a size new to obtain original optical effects and a design of different shape, while retaining the intensity of the shine and fire of the sizes "Brilliant" known, and while seeking to facilitate the size and increase the accuracy of the latter.
- the invention is characterized for this purpose by the characteristics appearing in the second part of claim 1.
- the gem thus cut, sends back to the observer an image with a play of light reflections and six-pointed star differential colorings where the rounded protruding portions separated by rounded hollow portions send shimmering, original optical effects to the observer allowing to obtain a facilitated size and a quality of facet size improved and high accuracy.
- the invention also relates to a method for cutting a gem, characterized by the fact that all the facets of the crown and cylinder head and then cut the lobed periphery of the rondist by performing the lobed shape with six rounded protruding portions and six rounded intaglio portions.

- the third and fourth facets 27 and 28 on the one hand and on the other of the rondist make an angle of 30 ° and 42 ° with the plane of the rondist 12.
- the method of cutting this gem firstly involves obtaining of the table, by cleavage parallel to one of the faces of the octahedron and then, after the bruting, the size of the different facets of the crown and the breech.
- This cut is made of preferably using a laser cutting device.
- the surfaces of cutting of the rondiste 12 are then polished and cleaned until all traces of carbon black spots due to laser burns have missing.
- the weight of the cut diamond retains about 25 to 30% of the weight of the cut diamond. rough diamond; this size therefore does not have a high yield.
- diamonds cut according to this size allow to obtain total reflections internal with hexagonal and lobed image structure and shape, which gives the gem new and original optical effects.
- This symmetry hexagonal combined with total internal reflections on the facets of the breech and a differential refraction on the facets of the crown allows obtain a remarkable and original fire due to its hexagonal distribution and peripheral lobes.
- the second embodiment illustrated in FIGS. 5 to 7 also includes a crown 10 and a cylinder head 11 separated by a rondist 12.
- the assembly also has a hexagonal geometric shape with an axis of symmetry hexagonal central 14 around which the facets are arranged in a hexagonal symmetry.

- the height H between the apex 50 and the base 61 is between 0.5 and 0.75 times the outside diameter D of the rondist 12.
- this height H, that Ht of the crown and that Hc of the cylinder head are 0.52 D, 0.18 D and 0.35 D.
- the first 55, respectively second 56, respectively third 57, respectively fifth facets 59 do with the plane of the rondist of angles between 8 ° and 20 °, respectively 20 ° and 27 °, respectively 20 ° and 32 °, respectively 30 ° to 50 °.
- second and fifth facets 56 and 59 on either side of the rondist make a 23 ° and 34 ° angle with the plane of the rondist 12.
- the cutting process is similar in that the facets are first cut of the crown 10 and of the cylinder head 11 around the hexagonal axis 14, which corresponds to the crystallographic ternary axis of the diamond, and that we then cut the lobed perimeter of the rondiste preferably with a laser.
- the embodiments described above do not have no limiting nature and that they can receive any modifications desirable within the framework as defined by claim 1.
- the cutting according to the invention can also be carried out on other stones and gems with similar refractive index and dispersion, or roughly equal to that of diamond. It may be necessary to adapt the angles of inclination of the facets taking into account the refractive indices of the substitute stones. Thus, the angles of the facets can also be changed according to the shape of the rough stones. Other additional facets can be added. These facets may only be as appropriate number of three per type of facets. The cutout of the rounder may also be obtained by any other suitable means.
