Abstract

The utility model relates to a diamond structure, in particular to an octagonal diamond structure with a hearts-and-arrows inside. The octagonal diamond structure with the hearts-and-arrows inside comprises a reversely-cut regular octahedral cone-shaped crown portion and a regular octahedral cone-shaped body, wherein the intersecting positions of adjacent sides of each upper bottom face of the crown portion and sides of the regular octahedral cone-shaped body are provided with starshine reflecting faces. Face foot reflecting faces are arranged from the midpoint position of each side to the lower bottom face of the regular octahedral cone-shaped body. Five/six positions from the midpoint of each side of a regular octahedron of the regular octahedral cone-shaped body to two lateral sides form main foot reflecting faces. By means of the cutting face structures, the diamond consumption is reduced in the cutting process, overall cutting steps are decreased, a cutting procedure of a hearts-and-arrows diamond is simplified, and the product cost is reduced.

Description

Inside is the octagon diamond structures of eight hearts, eight arrows

Technical field

The utility model relates to a kind of diamond structures, and especially a kind of inside is the octagon diamond structures of eight hearts, eight arrows.

Background technology

Raising along with people's living standard, bullion has obtained using more and more widely as people's ornaments, wherein particularly outstanding with Diamond Jewelry, especially diamond ring, except the decoration function of common ornaments, in people's marriage activity, also has the meaning intension that common ornaments do not possess, and along with the development that is cutting technique, the diamond that presents eight hearts, eight arrow radiance after the light catadioptric in diamond inside is subjected to liking of user deeply, general as the high-end cutting mode in the diamond, but because the cutting face of eight hearts, eight arrow diamonds is numerous, existing cutting technique not only cutting technique is complicated, and very large to the loss of diamond, general above 65-70%, so eight hearts, the eight arrow diamond product costs that cut out are high, cause price to exceed much in the diamond of other cutting modes.

Summary of the invention

The utility model provides a kind of cutting step few, and the loss of product is low, and the inside that reduces cost is the octagon diamond structures of eight hearts, eight arrows.

To achieve these goals, the utility model adopts following technical scheme:

It comprises positive octahedral ladder taper bizet and the positive octahedral conical body of a reverse cut, and the positive octahedral centrum of the adjacent edge of described each upper bottom surface of bizet and face arris intersection is provided with the star reverse side; Be provided with face foot reverse side by every arris midpoint to the positive octahedral cone of face bottom surface; The mid point on every limit of the octagon of described positive octahedral conical body forms main sufficient reverse side to the 5/6 place cutting of both sides arris.

Preferably, cut a wall between the positive octahedral cone of described master and the positive octahedral centrum of face.

Preferably, the described 1%-3% that highly accounts for whole height that is partitioned into.

Preferably, the conical surface of the positive octahedral cone of described master and horizontal plane angle are 40.6 °-41.3 °.

Preferably, the conical surface of described positive octahedral centrum and horizontal plane angle are 32 °-35.5 °.

Preferably, described horizontal bottom surface area accounts for the positive octahedral cone of face area 55%-62%.

Owing to adopted said structure, inside of the present utility model is the octagon diamond structures of eight hearts, eight arrows by each cut surface structure, not only reduced the loss of diamond in the cutting process, and reduced whole cutting step, simplify the cutting flow process of eight hearts, eight arrow diamonds, reduced the cost of product.

The specific embodiment

As Figure 1-3, the octagon diamond structures that the inside of present embodiment is eight hearts, eight arrows comprises positive octahedral ladder taper bizet 1 and the positive octahedral conical body 2 of a reverse cut, and adjacent edge 11 and the positive octahedral centrum of face arris 12 intersections of described bizet 1 each upper bottom surface are provided with star reverse side 13; Be provided with face foot reverse side 14 by every arris 13 midpoint to the positive octahedral cone of face bottom surface, after face foot reverse side 14 cut out, arris 12 was cut off, so dot; 21 mid points on every limit of the octagon of described positive octahedral conical body 2 form main sufficient reverse side 22 to the 5/6 place cutting of both sides arris.

In order enlarging into the light face, to increase fiery color effect in addition, in the present embodiment, to cut a wall 3 between the positive octahedral cone of described master and the positive octahedral centrum of face, the described 1%-3% that highly accounts for whole height that is partitioned into.

In the said structure, the conical surface of described positive octahedral conical body 2 and horizontal plane angle [alpha] are 40.6 °-41.3 °.

In the said structure, the conical surface and the horizontal plane angle beta of described positive octahedral ladder taper bizet 1 are 32 °-35.5 °.

In the said structure, described positive octahedral ladder taper bizet 1 upper bottom surface area is the 55%-62% of bottom surface area.

The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
