Abstract

The utility model discloses a jewelry diamond. The platform width ratio of the jewelry diamond is 65.40% to 60.00%, a crown height ratio is 12.10% to 13.50%, a pavilion depth ratio is 44.60% to 44.20%, a total depth ratio is 56.70% +a to 57.70%+a, a crown angle is 35 DEG to 34 DEG, a pavilion angle is 41DEG 45' to 41DEG 30', and a is 2% to 4.5%. Under the premise of reasonably adjusting the optical effect of the jewelry diamond, the utility model enhances the productive ratio of the jewelry diamond and makes processed diamonds achieve the unification of a decorative effect and economy.

Description

A kind of Jewelry diamond

Affiliated 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, the surface is general a typical adamantine luster, 20% jewel level tcrude ore is arranged in the diamond mineral products approximately, work with great care into Jewelry diamond, just can make it to send flash of light as the impayable rainbow and dazzling by the polishing teacher.Diamond is a kind of rare, expensive, natural resources that can't refigure, and generally speaking, the product of every carat of jewel level tcrude ore becomes rate to be about 1/3rd.Therefore, how under the prerequisite of the optical effect that guarantees diamond, the product that improves diamond becomes rate, and to realize the maximum value of diamond, " because of material is executed skill " is the cardinal principle that diamond processing designs.Diamond is chosen, if bias toward the weight of diamond, or biases toward the fire color (ideal is cut mill) of diamond, all is difficult to embody product function and maximum value.

The utility model content

The purpose of this utility model provides a kind of under the prerequisite of the optical effect that guarantees diamond, and the product that improves diamond becomes the diamond of rate.

For achieving the above object, the utility model is taked following design: a kind of Jewelry diamond, the wide ratio of the platform of described diamond is 65.40%～60.00%, the crown height ratio is 12.10～13.50%, booth is dark in 44.60%～44.20%, entirely deeply than 56.70%+a～57.70%+a, and 35 °～34 ° at hat angle, 41 ° 45 '～41 ° 30 ' at booth angle, a is 2%～4.5%.

The utility model is rationally being regulated under the prerequisite of optical effect of diamond, and the product that improves diamond becomes rate, makes the diamond of processing reach the unification of decorative effect and economy; Increased the lightness of diamond, the diamond that some colors are owed slightly has the effect that improves optical effect of diamond; Because the increase of table top and the raising of lightness, diamond complete dark than less relatively, therefore, the profile of identical weight diamond is bigger.

Description of drawings

Below in conjunction with description of drawings embodiment of the present utility model is further described.

The specific embodiment

Diamond has very high refractive index and very strong chromatic dispersion, and its original crystalline form generally is octahedron, granatohedron or other combinate form (see figure 2).The former stone of diamond is cut the standard round bur of wearing into 58 faces by certain physical dimension design, about 17% incident light quantity is directly reflected by diamond surface, and about 83% incident light quantity enters the optical system in the diamond after rational faceted pebble reflection presents due optical effect.The combination of every rate value of diamond has a scope, and is color for the bright and fire that shows each diamond as much as possible, pursues the unification of decorative effect and economy simultaneously, and the combination of the every rate value of diamond must be rationally.The desirable mill ratio of cutting can reach and is close to perfect optical effect, does not reach decorative effect and economy unified demand but meet the former stone of considerable part diamond.Along with the requirement to popular variation with people of popularizing of diamond jewelry, the product that improves diamond becomes rate, reduces product cost, seems particularly important.The utility model is seen following form for the diamond that adopts the processing of sawing scheme with three kinds of every ratio designs of embodiment:

Specification	A	B	C
Specification	A	B	C	Diameter D	100.00％	100.00％	100.00％
The wide d/D that compares of platform	65.40％	62.00％	60.00％	Diameter D	100.00％	100.00％	100.00％
The wide d/D that compares of platform	65.40％	62.00％	60.00％	Crown height compares h ₁/D	12.10％	12.80％	13.50％
Booth is deeply than h ₂/D	44.60％	43.90％	44.20％	Crown height compares h ₁/D	12.10％	12.80％	13.50％
Booth is deeply than h ₂/D	44.60％	43.90％	44.20％	Entirely deeply than H/D	56.70％+a	56.70％+a	57.70％+a
Hat angle α	35°	34°	34°	Entirely deeply than H/D	56.70％+a	56.70％+a	57.70％+a
Hat angle α	35°	34°	34°	Booth angle β	41°45’	41°15’	41°30’

Its middle part of the side thickness rate a is 2%, 3.5% or 4.5%.

The utility model is compared with European cut (SCAND.N.), and the bizet height reduces, and mesa dimensions increases, and to obtain the increase of diamond diameter, the diamond rate of producing into has increased 7%-14% thus.For replenishing the reflection clear area of diamond table, strengthen booth angle (see figure 7) slightly simultaneously.
