I dont think there is anything special in this toothpaste.
Its like other toothpaste of closeup. and according to me the taste of this paste is poor than I used before closeup product.
work like same as normal closeup tooth paste.
not much brightness for teeth.
price is more than its work.
freshness is good but not so good
Over all I think normal closeup paste is better than this paste. there is nothing better or good in this paste. there is just name of diamond nothing else.
