Emerald value if died

Hello everybody. Need your help to price those big emeralds. Their total carat weight is 50.37ct, but they’re heavily included and opaque AND DIED! The provenance is unknown and the color is a vslbG 7/4
According to the different price guides I’ve looked at, if I don’t take into account the treatments and dyeing, I would be around 50$ per carat. Is that right? It gives me a total of 2528$… which sounds a bit too much for me. What do you think?
Also: does anyone know Westfield Jewelry Appraisals? Are they reliable?
Thank you so much in advance for your help

Hi
I don’t know if this is useful or even accurate information. I live in the UK so checked your appraisers on the net. I couldn’t actually find a website (which would personally make me wonder) but did find a facebook page, I am not techie and that would sort of make me wonder again. I do not know if they are the same people but they certainly look the same, I did however find a lot of complaints about a company of the same or very similar name. You may want to check this out a little more thoroughly.
