In repolishing, what is the ultimate relationship to weight compared to recutting?

Explanation:
The main idea is how much material you remove to fix surface issues without changing the stone’s shape versus actually reshaping it. In repolishing, you’re simply smoothing and removing minor surface scratches to restore luster, which means you only take off a thin outer layer. That keeps the overall proportions and geometry intact and leaves most of the original weight in place. Recutting, on the other hand, involves reshaping and re-cutting the facets, angles, and dimensions, which requires removing a much larger portion of the diamond. So, compared to recutting, repolishing takes a lot less weight.
