Description

Diamond with double-five-star pattern seen from facet

Technical Field

The utility model relates to the field of jewelry, in particular to a diamond which presents double-pentagram patterns when seen from a facet.

Background

With the improvement of living standard of people, jewelry is more and more widely used as ornaments of people, wherein the diamond ornaments are particularly prominent. The quality of diamonds is evaluated mainly from four aspects, color, clarity, weight and cut. Since color, clarity, and weight are properties of the diamond itself that cannot be changed during its formation, only cutting can give the diamond better quality and value, and a more brilliant brilliance. With the continuous development of cutting technology, consumers have been unable to meet the traditional diamonds with hearts and arrows inside. Thus, a wide variety of diamond varieties such as heart-shaped diamonds, cupid-shaped diamonds, and pentagon-shaped diamonds, etc. are developed.

However, the existing pentagram diamonds are all single pentagram diamonds and do not have double pentagram diamonds.

SUMMERY OF THE UTILITY MODEL

In order to solve the deficiencies of the prior art, the utility model provides a diamond which presents double-pentagram pattern from the facet to the society, the small pentagram and the large pentagram in the diamond are staggered by 36 degrees, and the color of the second pentagram is darker than that of the first pentagram pattern.

The technical scheme of the utility model is that: the diamond which presents a double-pentagram pattern when seen from a facet comprises a crown part, a waist part and a sole part, wherein the sole part comprises ten large prismatic rake tip surfaces which are adjacent to each other, ten sole surfaces between the adjacent large prismatic rake tip surfaces and five small prismatic rake tip surfaces which are uniformly arranged by taking a rake tip point as a center, and the five small prismatic rake tip surfaces and intersected edges of the ten large prismatic rake tip surfaces are connected end to form a first pentagram pattern; each first corner A of the first pentagram pattern is provided with a small sole surface, two sides of each small sole surface are respectively provided with a small sole surface, the sharp point of the small sole surface corresponding to the first corner A of the first pentagram pattern and the sharp point of the small sole surface are overlapped, the five small sole surfaces refract a second pentagram pattern which is smaller in area and darker in color than the first pentagram pattern on the facet, and the included angle between the connecting line of the first corner A of the first pentagram pattern and the scraping sharp point and the connecting line of the second corner B of the second pentagram pattern and the scraping sharp point is 36 degrees.

As an improvement to the present invention, the crown comprises a central facet around which ten triangular facets are provided, for which twenty upper waisted triangular faces are provided near the upper waisted circle, ten main crown faces being provided between the triangular facets and the upper waisted triangular faces.

As an improvement to the present invention, the crown comprises a central facet around which ten triangular facets are provided, for which ten waisted triangular faces are provided near the waisted circle, ten main crown faces being provided between the triangular facets and the waisted triangular faces.

As an improvement of the utility model, the angle for polishing the small prismatic pickoff tip surface is selected within the range of 35-38 degrees; the angle of the small sole face is selected within the range of 42-44.5 degrees.

The utility model discloses when observing under the surely light mirror, present a big one little two pentagons effect on diamond's facet, and second pentagon colour is darker than first pentagon pattern, little pentagon in the diamond 36 degrees with big pentagon dislocation.
