OVAL (CHANGE 1)

This design is a variation of the traditional oval cut. It is distinguished by the presence

Of 16 additional facets, 8 of 8 on the crown and the pavilion, the arrangement and the degree

Elevation angles provide it with more brilliance and greater weight retention.

This variant is designed to gems that have a high refractive index

(Garnet, sapphire, spinal, ruby ...), able to withstand the considerable gap between the

Angles of the facets of the culet (9.90 degrees). Reproduction of the gems that have an index

Refraction less than 1.76 at the same time cause a butterfly effect, decreased

Considerable brightness and beauty of the stone.

FOUR TRIANGLES

The originality of this model lies in the line of the crown.

This table has a triangle whose contours are defined by the

Presence of three facets that is identical. This characteristic, rare

In the design of precious stones, is what earned him his name.

This design has 55 facets, 18 on the crown

And 30 on the pavilion. The superposition of the triangles of the crown and the star

Flag do very well out its brightness. Designed for a refractive index

Of 1.54, the angles chosen for reproduction refract light

Cut off. The crown, made up of 24 facets, is based on the size Radiant, invented

in 1976 by Henry Gross bard lapidary. The pavilion has a culet pointed, has 48

Facets, the arrangement and angles provide brightness reaches 80.7%. Reproduction

There is no particular difficulty with the exception of the size of facets on the upper floors

LACE ON RAYS OF SUN

This model, which is slightly rounded triangular shape, has light lines

And refined that give it an elegant and refined. Facets of the pavilion, slender

Like rays of light illuminate the delicate tints of their route to the crown,

Evoking the image of a tissue lace interspersed with sunshine.

This design will delight facetious who wish to achieve an economy of material.

The depth of the pavilion, as the elevation of the crown, is the least significant

And allow a reproduction of the model using a piece of gross whose thickness is minimal.

The difficulty level is high, however. His impressive number of facets (106) and

The delicacy of the lines starry flag requires the use of a gem

Whose final size will exceed 14 millimeters in diameter?

NEW ZINNIA

NEW ZINNIA

This model is based on a design developed for the size of the diamond: the Zinnia.

The original outline was replaced by an octagonal shape. Too delicate to be cut

Carefully by hand, facets starry flag, for their part

Been modified to facilitate its execution.

Plots flag give this design a good light.

The angles were changed and adapted to the size of a wider range of gems

(Garnet, sapphire, spinal, ruby ...), which have a refractive index lower than

That of diamond. They refract light in up to 84.3%.

This model includes as a main difficulty the size of facets whose height

Is not determined by the presence of the intersection (meet points faceting). This is the case

A facet whose height must match the respective third pavilion and two-thirds

The crown. Novices faceting take care to replicate this model on a stone

Low value in order to overcome the difficulties and avoid errors at least

Expensive that would be likely to occur at the waist.

Preserving its traditional route and its original look.

This design works well for stones whose color is of medium intensity.

The elevation of the crown and adding depth to the pavilion are slightly out

Is low although the size of the culet facet, due to their

Discretion, require extreme care and precision.
