Severe painting and digging out result in which outcome?

• A. Hill positions of differing thicknesses and uneven scalloping around the girdle.
• B. Uniform girdle with consistent thickness.
• C. No effect on girdle.
• D. Better scintillation.

Answer: (A)

Severe painting and digging out disrupt the girdle surface in an uneven way, so you end up with irregularities along the edge. Material is not removed or restored uniformly, which creates raised, hill-like spots where the girdle is thicker and leaves the edge with inconsistent, scalloped impressions from the polishing. In short, the girdle loses uniform thickness and develops uneven scalloping around its circumference. This is a telltale sign of aggressive or improper modification. Uniform girdle thickness would require careful, even finishing; no effect on the girdle or a gain in scintillation wouldn’t reflect this kind of damage.
