Navajo Turquoise

Could anyone help me identify the type of turquoise used in this ring please?


I really like this ring’s old-timer look and the blue-black stone : )


Hi, the posted image is I am guessing over-exposed; at least on my monitor the blue (and black?) is a bit ‘washed’ out yet what perhaps you’ve come across in your hunt is an old specimen of Tyrone Turquoise…check out: NATURAL TYRONE TURQUOISE CABOCHON 4 CTS and see if that cab is similar to your stone…just saying…lovely ring!

Thank you @rita got your information. Here is a clearer picture. It does look like Tyrone turquoise.
