Specializing in Brookfield CD 162.1's, my research has shown this color not to be a common one. Blackish and amber stringy swirls in the dome make it interesting. I do not call it yellow green b/c it is green with a slight hint of yellow. It is more green than yellow - but not just straight light green. This is an unlisted color as the "Yellow Green" book listing refers to a darker shade that does not pass light as well as this one does (in fact, there is no light green listing either - and this one is on the lighter green side). Was 20.00 - Someone will get a nice piece at 12.00 plus shipping.
