Earlier in the week, we talked about white gold and how it is an alloy that included yellow gold with other metals. The inclusion of other metals changes the properties of the gold so that it is usually wither stronger or softer than it would have been it is normal state.
Rose gold was once all the rage in Russia and so it was known as Russian gold at the start of the nineteenth century. Now it is most often known by the more physically descriptive name of rose gold and sometimes called pink or read gold.
While white gold is not white in the way a piece of paper is, rose gold really does have a reddish or pinkish hue. This is because rose gold is yellow gold mixed in an alloy with copper. While white gold is often coated with rhodium to make it truly "white" and rid it of any brownish tint, rose gold doesn't need extra coloration to become reddish. However, the amount of copper included in the alloy is what makes the difference in the deepness of the red. Less copper make the gold pinkish and more copper means the gold with be closer to red.
As if this was not confusing enough, the music world employs the term rose gold for something that is not really gold at all. a layer of silver, covered with a layer of copper is used as a finish for the inside of some woodwind instruments. There is no gold, but the use of a copper alloy and the resemblance to rose gold helped this term catch on, even if the rose gold on the inside of a musical instrument is fool's gold in a sense, since it isn't real gold.
So be advised that you cannot present any woodwind instruments to a gold buyer in an attempt to sell gold. You can, however, present objects such as jewelry made from yellow gold and other gold alloys if you want to get cash for gold.
