What effect does excessive bulge on a step cut have on the gemstone?

Excessive bulge on a step cut gemstone contributes to an increase in the stone's overall weight. The bulge effectively adds volume to the gem without proportionally enhancing the face-up appearance or visual appeal of the stone. In gem cutting, the design and proportions play a significant role in how light interacts with the gemstone, affecting brilliance and overall aesthetic. However, a bulge that is too pronounced does not enhance clarity or color; instead, it can lead to challenges in light performance, potentially masking the true beauty of the gemstone.

While excessive bulge may mistakenly give the impression of a larger size, it does not truly increase the overall dimension or surface area visible when viewed from the top. Hence, the primary effect of excessive bulge is the additional weight it imparts to the gemstone, which can impact the overall market value and desirability of the piece.
