Need help with tanzanite Appraisal

[tanzanitestone]

I was lucky enough as a child to visit africa: when i did back in the 70''s my family and I picked up a massive amount of blue tanzinite top quality gems. I have recently open my safe deposit box noticing they are there. Most are above 10 carats, and as far as i can tell flawless according to the information i found on Tanzanite web-sites.

My question is who is the best tanzanite appraiser in the USA that i can visit to have these stones appraised for value?

Thank you

Richard Sherwood! He’s very highly recommended for all varieties of coloured gemstones.
