This item was introduced during the 410 Hollow Eve festival (2013).
Per GM Persida: A rare translucent gem of bright vivid green with blue and yellow iridescence, iahja naturally forms in long, thin, six-sided crystals that grow outward from certain copper deposits. Particularly large (more than about a half inch in length), intact specimens are exceedingly rare, and correspondingly expensive. As such, iahja is most commonly found in small chips and pieces used as decorative inlay, and the larger intact pieces are very rarely shaped beyond the slightest finishings (sic) since its natural shape is considered valuable and beautiful in and of itself.
