Which term refers to placing and finishing facets on a rough diamond?

Explanation:
Polishing is the finishing step that gives the facet surfaces their smooth, mirror-like planes. After the cutter has determined where each facet will go, polishing smooths away any tool marks and precisely refin(es) the facet boundaries so light can reflect cleanly. This final work is what ultimately yields the diamond’s brilliance and fire. The other terms refer to different ideas: coning is an older shaping technique, kerf is the width of material removed by a saw, and the rose cut is an antique facet pattern rather than the finishing of facets.
