Alabaster

Alabasters refer to a type of translucent or semi-translucent mineral that is prized for its ornamental value and its ability to be carved into various decorative objects. Alabaster is a form of gypsum, which is a soft mineral that is easily carved and polished to create a smooth surface.

There are several types of alabasters, with the most common being white alabaster. However, rare examples come in a variety of colours, patterns, and textures that make them highly sought after by collectors and artisans. Some examples of rare alabasters include:
