Dark jewellery, along with dark tattooes, dark beer and dancing in the dark, is cool again.
Even if you are not in this sort of things, dark jewellery comes up with a message that goes beyond the underground visual jargon of a cynical, suburban teenager.
Dark jewellery, for instance, helps you reflect on death and afterlife, can be part of your essential Cabinet of Curiosities in meta-fashion accessories.
You can wear them at night, of course, pretending you are not REALLY into this sort of morbid humour, but the best is to wear them while going to work, or at a business lunch.
Of course you must widen your eyes in utter disbelief if somebody, a colleague who just sat at the table with you, politely asks you if your are - may be - a little crazy. You must pretend that the metal exo-skeleton hand you are wearing is a new kind of advanced cast from MIT, and that you are actually recovering from a tunnel carpal operation.
It's weird! - you might add with nonchalance - it looks like a creepy piece of dark jewellery!
