Joshephine-Heckert- or Kralik, Monumental look alike Loetz 7624 decor vase, Late 1800, Early 1900

Hello Everyone.
As the difference to buy this vase by the seller description(Phanomen LOETZ 7624 , I bought it primary because i love it and second i was suspicious as this could be Heckert, awesome vase for study, even more happy today has I learn about it on another group who could be the potential glass house.
Green ground, with nice iridescent going to dark Green, Blue to Red toward the base with threads drawn to a point and spiraling upwards, but way less dense as the real Phanomen 7624 is.

This beauty stand at 10.25 inches tall by 5.50 inches wide, ground polished pontil with lot of wear at the bottom, from late 1800, early 1900
