Ended up with this chip during a bulk trade. Liked it, "appeared to be heavier than most" and very good condition.

Are certain diamond mold heavier than the rest. Is the third time I find a diamond that feels heavier and a "blank" diamond mold chip, same. Probably my imagination, have lots of that! Any idea??

Looked up origin and found only ?MT, any change on that?

Any idea of value?

Thanks for looking and any input!!
