- While pure gold is
yellow in color, colored gold can be developed into various colors.
- These colors are
generally obtained by alloying gold with other elements in various
proportions.
- To produce green gold,
varying amounts of silver, copper, and cadmium may be alloyed in
differing percentages to create a range of green gold shades.
- Gold in pinks to reds
requires varying amounts of copper and silver. Some gold colors,
such as purple
and blue, contain aluminum and iron, respectively.
- These gold colors are
much more difficult to produce but are stunning in appearance.
- Certain colors may be
limited to 10kt, 14kt, or 18kt. Generally white, rose, and yellow
gold are available in all three karatages.
- Research all necessary
application equipment, material and development needs of the
industry from concept and design to finished product in order to
enable speedy introduction to the market of new coloured gold's and
surface treated gold's.
- Mixing in silver and
copper is a bit of science-if too much silver is added, the gold
will show a green tinge. On the other hand, mixing in too much
copper will give gold a red tinge (so-called "rose gold").
- Addition of nickel or
palladium overpowers the distinctly bright yellow color of gold,
producing what is known as "white gold."
- Mixing other metals
with gold produces a variety of colored golds, such as green gold ,
pale yellow gold , yellow gold, red gold, and white gold.
- Rose gold is made by
melting gold with copper which is naturally reddish in color.
