Morphology
The meaning 'a diamond that is black in color' is directly and transparently composed from 'black' (colour) + 'diamond' (gem), following a straightforward adjective + noun pattern. Even if the gemstone is rare, the semantic combination is predictable and cross-linguistically common, so a B1 learner who knows the parts will understand it.
Etymology
Black diamond was used for rare stones that are dark and not see-through and look like small, shiny black rocks found in some places. That's why black diamond now means a rare type of diamond that is dark and not see-through.
