Hi
Found this while shucking after a dive
.  Would really appreciate any feedback on what kind of cap to put on it to use as a necklace - I was thinking gold/silver? thin band just down from the base???  Also, some opinions on monetary value? There seems to be such a wide/long range!  Its so beautiful I dont know if I could part with it anyway. Approx measurements 50mm x 27mm and it weighs 65 carats.  Thanks everyone
