Rose Gold
 Rose gold is such a pretty name, which comes from the light pink to reddish tinge to the metal. It's also known as red or pink gold and there is no real difference between the three except that retailers will use pink or rose to imply a softer, more romantic sense and red for a more vibrant, active feel. In reality rose gold is a gold alloy. It's approximately one fourth copper to three fourths gold and silver. Almost no jewelry on the market can be entirely gold metal because it's too soft or malleable to hold its shape. That treasured wedding ring of yours will start to dent and bend soon after it's bought if made of pure gold so goldsmiths mix metals in to harden it. Over the years they've experimented with adding other metals to add color and copper is one of them. Other colored alloys are white gold and green gold. White is made by adding nickel silver or palladium to make it look like Platinum. It became popular during the 1920's. Green Gold is a mixture of one fourth silver and three fourths gold without the copper which gives it a yellow-green cast. Rose gold and other alloys can be used to decorate jewelry. A well known type of gold jewelry is Black Hills Gold, which is produced by a number of manufacturers. It is defined by the pink and green gold flowers or grape leaves used in the design of the jewelry. White gold is often used in alternating patterns with yellow or rose gold on bracelets, rings or hoop earrings. Rose gold can be molded into flower shapes for broaches or pendants with leaves made of green gold. Of course there is no limit to the form or pattern of these gold alloys in jewelry.
