Improvable means what regarding a diamond's ability to improve clarity?

• A. Diamond that can be repolished to improve color to G.
• B. Diamond that can be repolished to improve clarity to a VVS1 or VVS2 grade.
• C. Diamond that cannot be enhanced by any treatment.
• D. Diamond that can be recut to increase carat weight.

Answer: (B)

Improvable describes a diamond whose clarity could be raised through finishing steps that remove or reduce blemishes and shallow inclusions. If a diamond is improvable, repolishing can clean up surface flaws and, in some cases, remove near-surface inclusions enough to push the overall clarity grade into the high end, such as VVS1 or VVS2. So the best description is that the diamond can be repolished to improve clarity to a VVS1 or VVS2 grade. This isn’t about changing color, and it isn’t about a treatment that cannot be done. It also isn’t about recutting to increase carat weight, which wouldn’t improve clarity and often lowers carat.
