"Orange peel effect" mainly due to the jadeite mineral hardness anisotropy
caused by: emerald cufflinks were aggregates like jadeite mineral mutual
orientation, resulting in the hardness of the polishing process is different,
the orientation of the low hardness of jadeite depression is relatively high
hardness orientation jadeite raised relative to a bump and the depression
relatively uneven surface, which constitutes the "orange peel effect". Broadly
speaking, emerald cufflinks must be green, agate red, and amethyst
violet.
Therefore, from the emerald cufflinks "orange peel effect" can also
be seen jadeite mineral aggregates size and combination with each other
relations. Should be noted that some of the emerald cufflinks articles and books
in the "orange peel effect" as a characterization of the emerald cufflinks B
goods, which is undesirable. The popular saying is that the color of the
cufflinks must have its original bluster. In fact, the "orange peel effect" in
the emerald cufflinks A cargo was more prominent, and the boundary between
uplift and depression gradually smooth transition; emerald cufflinks B goods due
to acid erosion of the jadeite mineral clearance of particles is very obvious,
the performance is not a smooth transition between the bulge and depression, but
there is a fissure separated to form interludes between each jadeite mineral
particles, like a spider web-like fracture lines, called "etching pattern and
"orange peel effect" significantly different.

"orange peel effect" emerald cufflinks B goods etching pattern, "floc" is a
transparent or translucent jade cufflinks by side light or bottom light
irradiation within the emerald cufflinks, some cotton wool material phenomenon,
also known as "cotton". "Floc" most jadeite mineral particles in the emerald
cufflinks gap caused cracks and impurity inclusions on light reflection optical
effect known as the "intergranular. Jadeite mineral columnar appear in the
emerald cufflinks "floc" are often elongated strip, and some can also display
the jadeite mineral profile, cotton interwoven; imitation jade cufflinks
products, such as quartzite jade albite foam sub-or quartz particles composed of
the composition of the minerals are large granular, observed floc sugar granular
characteristics; the Xiuyu cotton was massive. The gloss of the cufflinks should
be absolutely shattered, crystal clear and spiritual.

Cufflinks "Green" refers to the visual performance characteristics of
the main components of the particle size and mutual combination of relations of
the minerals jadeite jade cufflinks, only in the Emerald cufflinks such a
special mineral assemblages and mineral properties to appear. Therefore, the
emerald cufflinks "Green" observation is an important means of identification in
the course of trade of the daily emerald cufflinks the emerald cufflinks. The
second meaning is from the perspective of color blending of the cufflinks. The
skills of observation is: pay attention to observe the emerald cufflinks "fly
wing" in a relatively rough surface of the emerald cufflinks; polishing better
plane to observe the "orange peel effect" through the reflective surface;
transmitted light or side light irradiation under the observation of emerald
cufflinks internal characteristics of the floc. Fly wing refers to jade cuff
links one by one like flies wings bright white reflective surface when exposed
to light characteristics. It requires the gem of the cufflinks has its inherent
natural color. "Flies wings caused by the emerald cufflinks jadeite mineral
cleavage plane reflective, often elongated strips or irregular flakes basically
reflects the size of the columnar jadeite mineral and mutual combination
between. Emerald cufflinks jadeite mineral size and orientation in the light
turn the emerald cufflinks, different parts of the fly wing "of different sizes
of flash, one after another, is very characteristic. However, flies wings "are
not all the emerald cufflinks will appear, and its main incomplete in polished,
rough around the edges of emerald cufflinks plane performance; polishing intact
plane, especially the cambered surface is not will be able to show it.
An
emerald cufflinks "fly wing", "orange peel effect", "orange peel effect" is the
emerald cufflinks in polished plane through reflective
observation, there will be similar to the orange peel a different size and
direction of convex from the characteristics and depression.
