This extremely deep clitoral shaft piercing starts below the clitoris and just above the urethra, and then goes up through the clitoral shaft and exits at the top of the hood.

As an Isabella piercing intersects the shaft of the clitoris, it is considered to be high risk for nerve damage and is therefore extremely rare.

Nerve damage can result from piercing a clitoris that is too small or from piercing through the shaft of the clitoris and through the dorsal nerve.

The Nefertiti piercing was invented in response to the inherent dangers involved with the Isabella piercing.

Isabellas are usually pierced with custom made barbells usually in 16 to 14 gauge and 5⁄16 in to 7⁄16 in.
