Granite Onyx

It looks like you're asking about Traonyx Dark KM, which may be a specific brand or variation of onyx stone, possibly related to a particular supplier or designer. Unfortunately, there isn't a widely recognized or commonly known stone by that exact name in the general gemstone or mineral catalog. It’s possible that "Traonyx" could be a proprietary name or a unique type of onyx marketed under a particular brand, or it could be a more localized or lesser-known variant of onyx that isn’t as broadly documented.
