NOTE:
co =  Convoluted, with the ridges sometimes lace-like.  On this form, there is a tendency for the open tubes running down the interiors of the fulgurites to exhibit a slight curvature.              
op = The ridges are opposed, with the fulgurite tubes exhibiting a fairly flat cross section. On this form, the open tubes running down the interiors of the fulgurites are usually in fairly straight alignment.

The numbers in (   ) following the gram weights,
above, indicate whether the fulgurite tube is open
on one end (1), or open on both ends (2).  Pricing is
according to the following schedule:

 (1) $ 3.50 / gram < 20 gram sizes
 (1) $ 3.25 / gram  ≥ 20 gram sizes

 (2) $ 4.00 / gram < 20 gram sizes
 (2) $ 3.50 / gram ≥ 20 gram sizes
 

MINIMUM ORDER IS $25.00
