Vintage silver and inlay turquoise in diamond shaped authentic cufflinks, Native American jewelry

Vintage silver and inlay turquoise in diamond shaped cufflinks. Size is 1 1/8" x 5/8". Please zoom in on the photos to clearly view the craftsmanship of this item. NOTE: I HAVE NOT POLISHED THE ITEM. I felt it would be best to leave tarnished as I am not knowledgeable on the best and safest polishing products to use.
My aunt kept very detailed records and they purchased this item from the Dorothy Dalton LaTienda in Mesilla, New Mexico in Nov of 1963.
These native american jewelry items I am selling all belonged to my aunt and uncle. The only owner was them until I inherited them upon their passing and these items have remained unused and stored since I obtained them. If you are a collector of vintage native american jewelry, keep an eye out in my shop for more authentic items to be added. I will be selling more of their remaining collection a little at a time.
