Here in our little factory, we have a great volary of invisible aves. To make this cranious chest pin, we firstly dip one of our evanescent sparrow's crowns into sterling silver, rendering it now positively perceivable. Then we pavé set our beaky spicimen with marcasite for added visibility. Next we mount him on a hand carved authentic Whitby jet shield with Turtledove femora crossbones. Finally the back is hand engraved with the most elaborate and intricate inscription.
Note: no extant aves were harmed for the making of this jewel.
