Abstract

The utility model discloses a round diamond with seventy one facets, whose body is provided with a crown portion and a pavilion portion, wherein the crown portion is provided with ten main crown facets, twenty upper waist small facets and ten star small facets, the pavilion portion is provided with ten pavilion main facets and twenty lower waist small facets, the table percentage of said diamond body is 56-59.9%, the crown-height ratio is 13.51-15.5%, the total depth percentage is 56-64%, the crown angle is 33.5-35.5%, the pavilion angle is 39.5-41.5% and the edge thickness is 1.5-4%. The round diamond can improve diamond production rate and optical effect.

Description

71 facet round diamonds

Technical field

The utility model relates to a kind of Jewelry diamond.

Background technology

Diamond has very high refractive index and very strong chromatic dispersion, and the surface is general a typical adamantine luster, and 20% the former stone of jewel level of only having an appointment in the natural diamond being through the working with great care of polishing teacher, and just can send splendid brilliant radiance as the impayable rainbow.Though 57 facets " eight hearts, eight arrows " that enjoy favor are the perfect consummate technology that has represented the polishing teacher of cut.Diamond be a kind ofly cost an arm and a leg, natural resources that can't refigure, generally speaking, the product of every carat of jewel level tcrude ore becomes rate to be about 1/3rd.But, can not farthest represent the fiery coloured silk and the lightness of diamond, therefore because facet is less, how to become under the prerequisite of rate at the product that guarantees diamond, rational and effective improves the optical effect of diamond, represents the most bright radiance that glitter of diamond, is insoluble always technical problem.

The utility model content

The purpose of this utility model is to solve the problems of the technologies described above, and provides a kind of under the prerequisite that guarantees the diamond rate of producing into, improves the diamond of its optical effect.

The purpose of this utility model is achieved in that

71 facet round diamonds, diamond body have bizet and booth portion, and described bizet is provided with the main facet of ten hats, 20 last waist skill facets and ten star skill facets, and booth portion is provided with ten booth masters facet and 20 following waist skill facets; The wide ratio of the platform of described diamond body is 56%～59.9%, and the crown height ratio is 13.51%～15.5%, and full Guan Jiao is 33.5%-35.5% deeply than being 56%～64%, and the booth angle is 39.5 °～41.5 °, and the limit is thick to be 1.5%～4%.

The utility model can also adopt following technical measures to solve:

As optimal way, the center symmetry is adopted in the facet on the described diamond body, the mode of correspondence is evenly distributed on the bizet and the booth portion of diamond up and down.

The wide ratio of the platform of described diamond body is 56%, and the crown height ratio is 13.51%, and full Guan Jiao is 33.5% deeply than being 56%, and the booth angle is 39.5 °.

The wide ratio of the platform of described diamond body is 59.9%, and the crown height ratio is 15.5%, and full Guan Jiao is 35.5% deeply than being 64%, and the booth angle is 41.5 °.

The limit of described diamond body is thick to be 1.5% or 4%.

The beneficial effects of the utility model are:

The utility model is on the basis of existing 57 facets " eight hearts, eight arrows " standard cut, totally two ten four facets have been increased, and with each facet adopt center symmetry, corresponding mode is evenly distributed on the bizet and the booth portion of diamond up and down, the product that can improve diamond becomes rate, can effectively increase the color and lightness about 25% of fire of diamond again; Moreover, superior because of its technology and processing, symmetry is excellent, so under the cut mirror directly over the diamond tangent plane overlook, can see consistent, ten the bright and symmetrical arrows of radiance of size, then present ideal symmetrical, full ten hearts under the diamond---i.e. the effect of " ten hearts, ten arrows ".
