Gradient embossed nail designs are a popular trend in nail art. They involve layering different colors on the nails, creating a smooth transition between them. The embossed technique adds texture and depth to the design, making it visually appealing. To create a gradient embossed nail design, one would typically start with a base coat, apply a base color, followed by a gradient of colors, and finally add the embossed design using a special powder or nail art pen.
