diamondiferous

Those days in dark diamondiferous caverns were full of strange experiences.

Since that epoch the exploitation has been continued by lessees of the diamondiferous grounds.

The nuggets and diamond-bearing stones stick in the grease, but the non-diamondiferous pebbles pass over.

Well, of my thirty thousand tried acres, a hundred only are diamondiferous.

During 1909 various companies were formed to exploit the diamondiferous area.
