Yellow lab-grown diamonds are diamonds created in a lab that have a yellow hue. They are chemically and structurally identical to natural diamonds, but they are created in a controlled environment rather than mined from the earth.
The yellow colour in yellow lab-grown diamonds is caused by the presence of nitrogen impurities. The more nitrogen impurities present, the deeper the yellow colour will be. Yellow lab-grown diamonds can range in colour from light yellow to canary yellow.
