Any Medium culet size or smaller will be imperceptible to the naked eye, and make no negative impact on the look of a diamond.
An Extremely Thin girdle is more prone to chipping, and accordingly should be avoided for a diamonds that is meant to be set in a ring. Earrings or pendants are not as exposed to rough contact and thus are not as likely to chip around the girdle too. Even Very Thin girdles in Princess Cut diamonds must be avoided, since this shape already has sharp corners that increase the probability of chipping.

Finally, with Poor symmetry diamonds having defects visible to the naked eye, they should be avoided at all costs.
