What is the prescribed compensation for the total loss of a singular, unique body part?

Primary text

For any body part of which Allah created only one in a person, such as the tongue, nose, male organ (dhakar), or the back (sulp), a full Diyyah (blood money) is due. This is because its total loss results in the annihilation of the benefit associated with that entire species of part, which is equated to the loss of a life.
