Vintage Green Turquoise Stone Knotted Beads Necklace What Are They Gemstone

Strand of vintage green stone knotted. Beads are varying shades of green with sandy colour matrix. They are stone - they could possibly be a green turquoise with pyrite matrix - that's the closest I could see or maybe simply a green Agate?? If I have it completely wrong and you know better what they are please message me - would love to hear from you and solve my mystery and correct this listing - for now I can only offer them as simply green stone beads. Strand is knotted and measures 16 inches long.

Largest bead is 15mm and smallest is 7mm. This item is in the category "Jewellery & Watches\Fine Jewellery\Necklaces & Pendants".
