Hi experts! As a novice, I need some advice to understand what might be that gem. I received it in a small paper bag, as a gift for my collections of minerals and gems, with a couple of small rough diamonds, no jewеlry value, from a friend that works in a Johanesburg diamond centre. I know it's impossible to say for sure what it is, but I hope someone can help... It's a small 1,5 ct grain and and it's relative weght like diamond, but under 15x lens I see a nest of someting speciffic yellow like gold. I can't make a better picture... My friend said someone in the past left these gems in his office and never saw him again... Any suggestions?
Thanks in advance
and have a nice day!

It really isn't possible to tell from a picture, but my first thought, looking at it was "diamond". Then I read the text.

Looks almost like a Kingsford charcoal briquette...

Yes, I would go with boart, but remember, this is just a guess, based on a photo.
