Very Rare Deep Blue Base Clambroth

Condition: Mint –
Grade: 9.35
Size: 11/16″

Very Rare & Elusive Deep Blue Glass Clambroth from my personal collection with 17 White lines evenly distributed around the marble with fantastic symmetry. The micro white characteristics within the glass is a natural as-made feature, looks much better in hand than under magnification for the photos. Mint condition with only very minor handling, no chips.  A very very hard to find marble and rarely comes available on the market.
