I've got a 1.25ct emerald-cut Tanzanite -- it's set in a 14kt WG 0.37ctw diamond setting (ring size 9) -- it's a very pretty mostly Blue, sometimes purplish-Blue color -- very clean -- willing to sell loose or in the ring:
Gosh, sorry these pics are SO BIG -- anyway, if you're interested, feel free to contact me directly via my email which is in my LT listings https://loupetroop.com/users/marymm -- and no worries if this is not what you have in mind
