Beautiful, chunky green turquoise bead necklace by Jay King for Mine Finds (DTR). This retired style features large 15–18mm rondelle beads with distinctive black spiderweb matrix and natural golden host-rock accents — a classic hallmark of Jay King’s Mexican green turquoise collections. Note the length is not adjustable. The earrings do match the necklace - all .925 sterling - but I cannot find a DTR marking on the earrings. The earrings may be a coordinating, unbranded sterling green turquoise. Either way it’s beautiful.
