Identification summary

The Yellow Moss Agate is a quintessential Master Marble production from the 1930s. It is characterized by a 'mossy' or cloudy translucent base glass with a yellow patch or wispy swirl. Unlike the more common Akro Agate patches, Master Marble's Moss Agates have a deeper, more ethereal transparency in the base glass.
