What kind of stone is my owl carved out of a see thru white stone with a blue hue?

Your owl is likely carved from a type of stone called alabaster, which is a translucent white stone that can exhibit a bluish hue. Alabaster is known for its softness and ability to be intricately carved, making it a popular choice for sculptures and decorative items. Another possibility could be a form of calcite or even some types of quartz, like blue lace agate, which might also have similar visual characteristics.
