Identifying possible mine these cabs are from?

Recently got this old ring in a bundle purchase and have just fallen in love - I’m wondering possible mine - Turquoise Mountain perhaps? There are no marks.


I feel like with the age of the ring and the cuts of the turquoise you have Persian Turquoise.

Thank you Jason! It IS a very pretty robin’s egg blue with reddish brown matrix - regardless, I love it! :smiley:
