Vintage Native American "Kokopeilli / Kokopilau" Pin Sterling Silver Opal Lapis

Vintage Native American Sterling Silver Kokopelli / Kokopilau Pin. It features beautiful pieces of Bezel Set Opal and Lapis Lazuli. The stones are natural. More than likely this was crafted by either a Zuni or Hopi Artisan. I've had this piece for quite some time. And, sadly rarely wear it. It was purchased on a trip to Arizona quite some time ago. It is marked "Ster" For the life of me I cannot find a hallmark. The pin / closure functions wonderfully. It has been worn twice. And, it's in excellent / like new condition. I will do my best to take good pictures. The larger Opal really pops with reds, greens, a smidge of blue and purple. The smaller opal is mainly reds / greens. The Larger Lapis is a really deep Indigo Blue with flecks of gold. The smaller Lapis has the deep blue but no flecks. I did polish the pin a bit, just to get off some of the patina for photos. It could stand a bit more polishing. I won't be accepting offers on this particular piece. My price is firm on this item.
