This is a somewhat unusual situation. A while back, when my dad passed, I ended up with a dozen small emeralds, from about .5c to about 1.5c. As it happerns, I know they came from the Muzo district in Colombia a few decades back. While I know there was once documentation identifying the source, that stuff isn't around anymore. While I'd love to get certification of origin somewhere, what it'd cost at, say, GIA is just way too much as they aren't especially valuable stones. Saturation is fairly low for all of them, and what GIA would charge might even be more than some of them are worth. Anyone have any ideas where I might get a less expensive certification of origin for these dozen stones? I've attached a not so great pic of one which should at least give a general idea what they look like, except this one is maybe somewhat more on the heavily included end than most are. But it does show their color pretty well.
