Brazilian Emeralds in the Rough: Value & Selling Options

Question
I would like to know what something like this is worth as well as where to sell it.

Answer
HI PRUDENCE,

THERE ARE MANY VARIABLES THAT DETERMINE VALUE OF A SPECIMEN. THE GEM MATERIAL HAS TO BE EVALUATED BY ITS SIZE, CLARITY, WEIGHT, COLOR AND HOW IT LOOKS AS A WHOLE. THERE ARE SOME EMERALDS IN MATRIX THAT ARE WORTH MORE THAN IF THEY WERE CUT. SO IT IS IMPOSSIBLE TO ESTIMATE VALUE WITHOUT ACTUALLY SEEING AND INSPECTING THE SPECIMEN. THE BEST PLACE TO SELL SOMETHING LIKE THIS IS AT A GEM SHOW WHERE ALL THE BUYERS ARE SELLERS AND VICE VERSA.

THANKS
PETER
