Mint Vitro Agate Company Tri-Lite Marble, 5/8 inch, white base

This is a Vitro Agate company patch marble. It was probably sold under the Tri-Lite name, and was made in the 1930s. This 5/8 inch marble is a bit unusual for a Tri-Lite in that the base is a solid opaque white with no clear glass present. The surface is wet and glossy with a few tiny air bubble dimples, and under magnification it has a few tiny flea bites, so grades Mint-.
