Abalone Shell Nightlights. Glowing beautifully at night to add a little light to any room. Every shell will be slightly different due to nature. We will send you an Abalone Shell Nightlight that will be just as nice as the one pictured, but may not be the one pictured. The Small Red Abalone shell has been polished. It is considered a small red Abalone, but the color varies on every shell. The Green Abalone has some Browns and reds and has a clear coating on the shell.
