Mint Akro Agate Silver Oxblood and Eggyolk Corkscrew Marble

This is a excellent looking of Silver Oxblood and egg yolk corkscrew marble. It was of course made by Akro Agate. It is great condition, and features a good corkscrew pattern. It is whisker over 5/8 inch (measured with calipers). It has the characteristic silver translucent base with filaments characteristic of the Akro silver oxbloods. The marble has some air bubbles in the glass, and a few tiny dimples. It also has the tiny chip that you can see in the last picture in magnified view, a fleabite under magnified view, and a couple of tiny sparkles visible in the right light. Despite the very minor marks it still grades Mint 9.4 condition.
