This is both the largest AND only all blue millie marble from Josh that I've ever seen or sold. This gem is truly amazing, one of those that I'm secretly hoping won't sell, because I'm happy either way. The amazing millie that Josh created absolutely POP against that beautiful blue base, and then that opal just highlights the majesty of the marble. These are some of Josh's finest millie ever, and this is flat out one of Josh's best marbles ever. I'm going to stop talking about it, because otherwise this one will slip into my pocket and I'll mark it sold. Shutting up now.... Signed 'Sable 2014'.
