Hi, Tplink

Second piece is a glass/melting slag.
And first, probably same for company....

No minerals...

With best wishes

Lluís

Top piece looks like fluorite with a secondary coating.

Yes, I agree with Lluis on the second, dark and glassy example.

It is slag glass.......not natural.

The first light colored one, I am not sure about. BOB

Rather sure that none of those are diamonds. The dark ones are slag glass. A diamond tester would not be my first choice for mineral identification.

Sorry to say Tplink, but there are no kimberlites (diamond-bearing host rocks) within several thousand miles of Nottingham.

Pretty sure the jeweler is going to confirm man-made furnace slag...

It's all just furnace slag. I've seen tons of the stuff used as rail track ballast, farm tracks and every other use they could think of to get rid of it. The north and midlands of England produced many millions of tons of iron from both local and imported ores. Sixty years ago I found a black, glassy piece on a farm track and showed it to my geography teacher at school. I thought it might be obsidian but he quickly put me right. That find started a lifelong fascination with rocks and minerals. It's good that Tplink wants to know what they have, assuming it's not a wind-up, but the obvious answer to a question is usually the right one.
