I'm new to collecting minerals and was wondering if someone might have an idea what the material is surrounding the emerald and if this can be cleaned/removed slightly near the emerald to make it stand out more. This emerald is supposedly from South Africa. I also have another one similar to this from Columbia.

The black material is probably mica/schist. Removal requires some sort of physical process, most likely air abrasion.

In general very hi end emerald specimens, because of their potential collector or jewelry value, are given to recognized prep labs to be cleaned and prepared. If the example is worth a lot, cleaning and preparing it might cost $$$. For a novice to try and do this risks ruining the specimen. CHEERS.......BOB
