Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a gem, in particular to a heart-shaped gem with higher brightness.
[ background of the invention ]
The round diamond cut is the most common shape of a gemstone cut, which typically has better brightness, dispersion, and scintillation. While heart-shaped cutting is a novel gem cutting (as shown in fig. 8-13), the existing heart-shaped gem has poor light gathering effect due to the fact that the shape and the structure are not optimized, and the appearance is poor brightness, low dispersion, poor fire effect and weak flicker of the product. Therefore, it has been a pursuit of those skilled in the art to improve the brilliance, scintillation, and sparkle effects of heart-shaped gemstones.
[ Utility model ] content
The utility model aims at overcoming the defects of the prior art and providing a heart-shaped gem (eternal heart) with higher brightness, higher dispersion, stronger twinkling and better fire effect.
In order to achieve the above object, the utility model provides a heart-shaped precious stone that luminance is higher, constitute by crown 1, waist 2 and pavilion 3, crown 1 sets up the crown facet including the mesa 11 that is located the top between mesa 11 and the waist 2, and wherein, pavilion 3 is divided into pavilion 31 and pavilion 32 down by middle part arris 33, and pavilion 31 includes a plurality of pavilion facets 311 of going up, and pavilion 32 includes a plurality of pavilion facets 321 down, the contained angle of going up pavilion facet 311 and waist 2 is greater than 60, the contained angle of pavilion facet 321 and waist 2 is less than 45 down.
In the present invention, for convenience of description and not limitation, the direction in which the table top is located is referred to as a horizontal direction, and in a direction perpendicular to the table top, the direction toward the table top is referred to as "up" and the direction toward the pavilion portion is referred to as "down".
In the present invention, the angle between the pavilion facet 311 and the waist 2 is the angle α between the pavilion facet 311 and the horizontal direction, and the angle between the pavilion facet 321 and the waist 2 is the angle β between the pavilion facet 321 and the horizontal direction.
In the present invention, the crown facets include a first-level facet 12, a second-level facet 13 and a third-level facet 14, the first-level facet 12 is triangular, each first-level facet 12 and the table 11 have a common edge, the second-level facet 13 is disposed between two adjacent first-level facets 12, and the remaining crown facets are the third-level facets 14.
As a preferred embodiment, to further enhance the brilliance of the stone, the waist 2 preferably has a waist facet 21.
As another preferred embodiment, the pavilion facets 311 are approximately quadrangular, and the common edge of the quadrangle and the waist 2 is a broken line or an arc line. But the pavilion facets 311 in the respective positions may also take a shape approximating a triangle, particularly when the pavilion facets 311 are located in a recessed area of a heart-shaped gemstone.
To increase the brightness and make the gemstone more glittering, the pavilion facets 321 are triangular or quadrilateral.
In the present invention, the gemstone has a maximum cross-sectional area at the waist 2, and the cross-sectional shape of the waist 2 is heart-shaped.
Preferably, the height h3 of the waist 2 is 5% -10% of the total height of the gem; the height of the pavilion-mounting facet 311 is 25% -40% of the total height of the gem; the pavilion facets 321 have a height of 25% to 40% of the total height of the gemstone.
Compared with the existing heart-shaped jewel, the higher waist, the upper pavilion facets and the lower pavilion facets change the appearance shape of the jewel, and the jewel is more elegant and heavy visually. The arrangement of the pavilions as the upper pavilion facets and the lower pavilion facets can significantly improve the internal reflection, thereby obtaining higher brightness and flicker.
Preferably, the mesa 11 is an n-sided polygon, the number of primary facets 12 is equal to n, n ≧ 6n is a natural number. The number of pavilion facets 311 is not less than 2 (n-1). Increasing the number of primary facets 12 is advantageous in improving the brilliance of the stone. One skilled in the art can select an appropriate value for n depending on the product size of the gemstone. Further, when the waist portions are provided as facets other than the arc surfaces, it is preferable that the number of the waist facets 21 be equal to or larger than the number of the pavilion facets 311 × 2.
The heart-shaped jewel (permanent heart-shaped) of the utility model effectively improves the refractive index of the jewel and the fire color through the structural improvement, so that the jewel is brighter and brighter; meanwhile, the gem is more plump in shape and has fashionable aesthetic feeling.
Compare with traditional heart-shaped structure precious stone (like fig. 8-13), the utility model discloses a precious stone has thicker waist, and facet number below the waist increases, and pavilion portion is pavilion portion and lower pavilion portion by middle part arris, and pavilion portion tangent plane and horizontal plane contained angle increase to make the whole shape of product more elegant and strong, the internal reflection effect of light is better, and luminance is showing and is improving.

[ detailed description ] embodiments
The following examples are provided to illustrate, without limitation, the technical solutions of the present invention.
Example 1
A heart-shaped gemstone, as shown in fig. 1-6, is comprised of a crown 1, a girdle 2 and a pavilion 3.
The crown 1 comprises an octagonal mesa 11 at the top, with crown facets between the mesa 11 and the waist 2. The crown facets are divided into a primary facet 12, a secondary facet 13 and a tertiary facet 14, the primary facet 12 being the face adjacent to the mesa and the 8 primary facets 12 each having a common edge with the mesa 11, as shown in figure 3. Between two adjacent primary facets 12 are secondary facets 13, and the remaining crown facets are tertiary facets 14. The secondary facets are mostly quadrangular, but the shape of the secondary facets close to the recessed region 4 is adapted.
To increase the brightness, the elevation of the waist 2 is faceted.
Pavilion 3 is divided into last pavilion 31 and lower pavilion 32 by middle arris 33 in the utility model discloses in, it is close with lower pavilion 32 height h3 to go up pavilion 31 height h2 for the precious stone wholly appears elegant and solemn, also is favorable to obtaining better luminance.
The pavilion 31 includes 16 pavilion facets 311, and the included angle α between the pavilion facets 311 and the waist 2 is greater than 60 °. The pavilion 32 includes a plurality of pavilion facets 321, and the pavilion facets 321 form an angle β of less than 45 ° with respect to the girdle 2. The optimization of the included angle also facilitates a better brilliance of the gemstone.
Most of the upper pavilion facets 311 approximate a quadrilateral in which the common edge with the waist 2 is a broken line (when the waist is set to a curved surface rather than a facet, the common edge should be an arc). However, the pavilion facets 311 at the respective locations may also be approximately triangular, particularly when the pavilion facets 311 are located in the recessed areas of a heart-shaped gemstone, as shown in fig. 2.
The utility model discloses a heart-shaped precious stone passes through institutional advancement, especially design of waist, facet quantity increase below the waist, and pavilion portion is divided into pavilion portion and pavilion portion down by the middle part arris, pavilion portion tangent plane and horizontal plane contained angle characteristics such as increase are showing and are improving luminance. Compared with the prior art, the heart-shaped precious stone made of the same material has the brightness obviously higher than that of the prior art in the same environment (sunlight), so that the shape structure is improved to improve the refractive index of the precious stone and improve the fire, and the precious stone is brighter and brighter; meanwhile, the gem is more plump in shape and has fashionable aesthetic feeling.
