A Note on Color: Each piece is hand-painted to capture the natural color variation of real stone, so no two pieces are ever perfectly identical. Colors can also look different on screen depending on your device, brand, and lighting. To make sure you get the color you want, we recommend ordering a sample first to confirm the color and material quality before placing a full order.
