Vtg Navajo Sterling Silver Turquoise Heishi Disc Reversible Choker Necklace

Native American Vintage Navajo Sterling Silver Turquoise Heishi Disc Large Reversible Choker Necklace This piece is thought to be the work of two different artists. The sterling is definitely Navajo and the rest is most likely Santo Domingo. Graduated Turquoise Heishi Discs in a double layer - I believe the turquoise is from a few different mines throughout this piece as the colors vary throughout. Sterling silver cone caps with hook & eye closure Six 1" long sterling silver tube bands, in 3 different widths One side has a rounded rectangular sterling station with a carved turquoise leaf on one side and two turquoise rounds on the other. All bezel set, surrounded by sterling pearl dots and swirl detail. 1.25" L x .5" H x .5" D The center piece has four bezel set turquoise rounds on one side (one of the pieces of turquoise has a bit of silver in it, possibly Morenci turquoise?) and the opposite side has a carved leaf and two rounds, all bezel set. Both sides have pearl dot and swirl detail Marked FC Sterling at the base Great condition with age appropriate wear. A couple of chipped discs, wear and tarnish to the silver. There is a 12- mark at the base of the center piece, looks like it was once written on with wax pen or marker. Overall a gorgeous, striking piece of Native American artwork. Hard to measure as it does not lay out flat, approximately 17" circumference around the neck. 6.8 Troy Ounces weight. Please feel free to reach out with questions.
