Daith piercing. A Daith piercing (pronounced DÃ¤TH) is an ear piercing that passes through the ear's innermost cartilage fold, the crus of the helix. In most areas this piercing is pronounced day-th which can be compared to the word faith, which is nonstandard. The standard pronunciation is doth like goth.
Generally speaking, though, the cost for an industrial piercing is likely to be lower in a more rural area than it would be in a bustling city. The reason is that property tends to cost more to rent or own in bigger cities, since shop space is in high demand, but available property is limited.
