 Yellow gold
is deemed as the quintessence of refinement and perfect manners, the sign of
perfect taste and style. Gold is available in red, pink, green, blue and even
black colors, though. Reputed jewelry houses employ all the shades to create
their accessories while colored gold is only seizing minds of ordinary
consumers. Average consumer still refers to colored gold as to the metal of
lower purity and quality.
Colored gold
was first employed by jewelers in the end of the XIX century when new metals of
precious group were developed as osmium, rhodium and palladium. Production
designers put some efforts and experimented with alloys. The color additive has
nothing to affect the quality and purity of the gold.
The jewelry
industry never uses absolutely pure gold. The .585 fine gold has 58,5% of precious
metal while the gold of .750 fine has the 75% metal, respectively. It is
interesting that most accessories from color gold come as gold of .750 fine.
The colored
additive is called alloy in jewelry sphere. And the shade of gold depends on
its composition. The most popular alloys are silver and copper.
White gold
The jewelry
items from white gold are ranked as reputable and worthy. It is often exploited
to trim diamonds. Palladium and platinum are used to make white gold. Yet, the
alloy differs from the natural platinum in color, with the slight tint of
yellow. Nickel is less expensive to add to white gold though reputed jewelers
quit using it since nickel often causes allergic reaction when contacted with
the skin.
Pink and red gold
When copper
is added to gold, pink and red shades are obtained for the more copper is there
in the alloy, the richer and deeper is the color. From old times red gold is used
to cast church domes and some time late it was practiced in making women’s
jewelry and accessories. Red and pink gold are known also as the love gold and
quite romantic and gentle jewelry is made from them.
Green gold
Silver,
zinc and palladium are used in equal proportions to obtain the greenish shade.
Green or olive gold is made when gold is alloyed with potassium. These alloys are
too fragile and are not, thus, appropriate to cast whole jewelry. Precious
stones are trimmed with yellow gold insertions and they are also used to
imitate floristic elements in jewelry design.
Blue gold
The
composition and technology of blue gold acquiring has been the secret for many
years as well as the black gold mystery. Some jewelry houses publish some
information at corporate web-sites on the gold obtained with the alloy of
indium or rhodium. The blue gold by the Argentinean jeweler Antoniassi who
obtained the alloy of .958 fine was found the real fable. The percentage of the
pure precious metal is over ninety percent. His colleagues suspect that the
designer added some cobalt to gold.
Violet gold
The exotic violet
color was attained by the intermetallic compound of .750 fine with aluminum or
potassium. This is not the alloy but the sol-called metallide. К unfortunately, the violet
gold has the disadvantage to all other color gold since it is incredibly
fragile and is used in jewelry as the insetting or imitation of faceted
precious stones.
Black gold
Black color
seems to be the most unusual for the precious metal. To obtain this shade, the
gold is mixed with cobalt and chromium simultaneously oxidizing the new
assembly at higher temperature. The surface is painted to black color with the
help of the black rhodium or amorphous carbon.
Black gold
looks benefitial when combined with other color gold, like alloy with classic
yellow, red and white.
Tendencies
by reputed brands
The jewelry
combination of cold colors, as clack, white and blue come to become the major
tendency of the jewelry world this season. Gold jewelry of appropriate color
gamut will also in favor.
The jewelry
house Chopard is still faithful to its traditions accentuating the white and
pink gold. The Frey Wille Company presented the collection of 18 Carat Jewelry
based upon rings and pendants styled hippies of the most adventurous shades of
color gold.
Boucheron, known
for its sympathy to black gold presented the new wonder – the ring from the
gold of chocolate tint created by the designer Solange Azaguri-Patridge. It is made as the chocolate
with the bite with B letter in the core.
The King of
jewelry, Cartier House with the Graf House demonstrated unique jewelry items
from white gold based upon yellow gold, though.
Gold is
still gold, whatever color it is and it is still the most popular and demanded
precious metal among others.
