Vintage Green Aventurine Bracelet

This vintage bracelet is made of a gold tone metal and has a c clasp closure. The bracelet features 18 small green-blue stones that I believe are green aventurine (due to tone, clarity, and the dark spotted inclusions). The inside of the bracelet has two rows of what appear to be an 'S' link chain. The stones range in tone from light green and transparent to dark green, but they all have the same kind of dark marks. The bracelet is not stamped anywhere I could see. There are two stones that each have a small crack or hit mark. If you look at picture 3 and start at the top, the first stone is the 3rd clockwise from the clasp (the mark on the right of the stone), and the second is 8th clockwise from the clasp (the mark at the very top of the stone and an invisible mark in the center of it). Other than the marks on these two stones, this bracelet is in good condition and very wearable. Length: 19cm / 7.5" Stone dimensions: approx 11x7mm Weight: 9.51g
