VINTAGE, Made in West Germany, these reverse carved picture stones are miniature works of art. Known historically as crystal paintings, each of these glass crystal stones is hand pressed with a smooth domed top through which you can see a detailed intaglio image, molded into the back of the stone. The intaglio carving is then painted or coated, and the surrounding surface is cut or polished to remove excess color and highlight the image. This scene has a painted color image on a painted base. Due to the nature of these stone, please take care when attaching, as the painted backs may be affected by different types of glue.
