What is the meaning of red gold? What kind of jewelry have been made of red gold? What kind of royal jewelry made of red gold have been used?
red gold is simply gold which is alloyed with copper which gives it a reddish color. Often called : pink gold or rose gold.
depending on the amount of copper used will determine the saturation of “reD” or “pink” color.
You can find tons of vintage and antique jewellery with this specific combination of metals at auctions and jewellery stores alike. If you are specifically looking for antique items from royal families or collections i would recommend looking through a museums exhibitions. Perhaps the Met.
Hope this helps.

Black Hills Gold jewelry is made of gold alloys resulting in pink/red, green colors… with the trademark feature being grape leaves and clusters. the color for red is due to extra copper being alloyed into the gold, reducing the gold content to 10k gold… green in made by alloying gold down to 18k or less with the addition of silver, purple and blue colors can be made with alloying with aluminum and iron at 18k or less…black highlights can be added by sulfiding the gold alloy… this kind of jewerly is mass manufactured in Rapid City SD at the present time…
If you are planning to buy colored gold, particularly Black Hills Gold, note that the karat is often 10k or at best 14k… the gold content of colored gold is less than 18k at the most and usually much less…be aware that the melt down value is far less than 24k gold…
Antique jewerly is an entirely different matter… the antique value is dependent on skilled worksmanship, as well as antiquity… Black Hills Gold modern colored gold is mass produced by stamping and soldering on an asyymbly line and has no antique value despite it’s looks.
