It is a \"Hikari\" set, and its special feature is that one of the \"Red Fives\" has been replaced by a \"Sparkling Diamond\" tile.
Question: How would you use this in play? Would you replace a 5-Coin with this tile and if so, how would you use it if you drew it? What benefit does it give you?
Does this tile appear as an option in any of the online or computer versions of Japanese mj that you play?
Thanks!
