Rose gold is basically a blend, or an alloy of pure 24 karat yellow gold, copper and silver. Pure 24 karat yellow gold is too soft to be used in a pure state for jewelry , hence it is alloyed with other metals to be in a wearable state.
Rose gold is a blend of gold and copper; the higher the copper content , the more rose pink color. As an example 14K rose gold is more of a rose pink color than 18K rose gold due to the higher yellow gold content in 18K. To create our lush red gold color known as rose or red gold, our 14 karat yellow gold is an alloy of 58.30% 24k yellow gold, 33.5% copper and 8.20% percent silver. Our 18 karat rose gold is a the color of a soft champagne rose, with gold undertones as the alloy is 75% 24k yellow gold, 22.2% copper and 2.8% silver.
