What made rose cuts efficient for use?

• A. The rose cut provided an efficient way to use flattened or cleaved diamond rough.
• B. The rose cut yields greatest sparkle.
• C. The rose cut is only used for fancy shapes.
• D. The rose cut was used to hide flaws.

Answer: (A)

The efficiency of the rose cut comes from how it uses rough diamond material. It is cut with a flat back and a domed crown made up of small facets, often with little or no pavilion below the girdle. This design preserves more of the original rough weight because you don’t have to carve away deep, complex facets or a deep cone below the girdle. In practice, rose cuts let cutters salvage flattened or cleaved rough that might not yield a modern brilliant, making better use of material that could otherwise be wasted. The result is a diamond that has a soft, top-light glow rather than maximum brilliance, but it was a practical, economical choice when material was scarce or irregular.
