What is the difference between rose gold and yellow gold?

From fashion magazines to Facebook posts, rose gold jewelry seems to be popping up everywhere, but is rose gold that much different from yellow gold? The answer is no.  When gold ore is mined from the earth it is yellow in color and extremely soft. In order to make it useable for everyday wear it is mixed with stronger alloy metals (the amount of alloy the gold is mixed with is noted by the  10k, 14k, 18k, etc mark).  Alloys metals commonly used in jewelry occur in a variety of colors and these colors are responsible for creating different colored gold. Rose gold jewelry gets a pinkish hue from copper added into its alloy mixture, but the amount of pure gold contained in each piece of jewelry is the same.
