Southwestern 14k/turquoise pendant

Southwestern 14k/turquoise pendant. Likely Native American, very well made piece with hallmark I don't recognize. The stone is greenish and untested, not 100% sure what it is but typically junk isn't set in a nice handmade 14k gold pendant. 1 1/8" with bail x .8" wide. All precious metals are tested and guaranteed, any Native American jewelry referred to as Silver or Sterling is guaranteed to be a minimum of 90% (coin) silver and possibly higher content. Anything marked is guaranteed to be what it's marked, most bracelets are photographed on a 6" wrist (non hairy), rings photographed on the appropriate sized finger when possible. With bracelets if the measurement is not given in the description then inside circumference is shown where the metal meets the number on the the cloth tape measure.
