Lab-Grown Diamond Clarity Chart: Understanding Purity & Brilliance Lab-grown diamonds, like natural diamonds, have clarity grades that indicate internal or surface flaws (inclusions or blemishes). The clarity chart ranges from Flawless (FL) to Included (I1, I2, I3), with grades such as VVS (Very Very Slightly Included) and VS (Very Slightly Included) in between. Higher clarity diamonds have fewer imperfections, ensuring superior brilliance and value. For more information please visit: https://blgdlab.com/lab-grown-diamonds
