Oh wait nvm... You're asking if it's specifically the 20K Lokani... With it being on that mari disc it's hard to say whether it's the Tyree 20K Lokani or not... Chances are it's a wild species with a similar coloration.
You can comb DD and find pieces that look like the true Hawkins Echinata and or Ice Fire Echinata, with them being plucked from the ocean without direct aquaculture lineage, I would personally just call them a wild Echinata. At any rate, you could still call it by the "named" look alike and be just fine.
