What is rose gold exactly? Well, rose gold, red gold, and pink gold as they are known are produced from a gold and copper alloy or mixture. Since copper has a bold pinkish/orange color, adding it to gold gives the gold a lovely pinkish gold color. 18K rose gold, 18K red gold, and 18K pink gold contain 75% gold content. 14K gold on the other hand contains 58% gold. The remaining percentage of metal consists of copper or copper and silver. The varying percentage of copper used determines the color of the gold and more copper that is used, the stronger the rose color. Pink gold uses the least amount of copper, followed by rose gold, and red gold has the highest copper content. The photo to the left is a custom 14k rose gold and diamond ring that we just finished.
