Sapphire Deep deep blue

Hello guys,
I have this 4,2 carat pear shape sapphire, royal deep blue.
Could somebody guide me on the price I could get.
There is no certificate but a suggested origin of Myanmar.
Thanks in advance,

if heated then + - $ . RETAIL1000 PER CARAT
IF NOT HEATED $ 3000 PER CARAT

Specially since it looks eye clean. I got one similar, but it’s a heart shape. About 4-5 cts. in weight.
