In rough diamond classifications, a Special refers to:

• A. A rough diamond under 1 carat
• B. A rough diamond over 10.80 cts, sold separately to a sight-holder who specializes in larger stones
• C. A polished diamond with a special cut
• D. A rough diamond priced for museum display

Answer: (B)

In rough diamond classifications, a Special designates a rough diamond large enough to require separate handling and sale. The key threshold is ten point eighty carats; stones at or above this size are scarce and are typically sold separately to sight-holders who specialize in larger stones. This setup reflects the rarity and value of such stones, and it ensures they’re directed to buyers with the focus and capability to deal in very large, high-value roughs. Smaller roughs fit into the regular lots, polished stones aren’t described by this term, and items intended for museum display aren’t categorized this way.
