Over 7/8″ Beautiful Very Dark Cobalt Mica with Loads of Mica

Condition: Mint –
Grade: 9.3
Size: 7/8″ +

Over 7/8″ Very Dark Cobalt Mica with loads of mica deep inside the marble.  This mica looks practically mint and much better in hand but has minor signs of use that become apparent with close up pictures.  Early faceted pontil dates this to before 1880.
