I don’t know anything about this. But it’s a higher grade silver. “970”. Features Malachite & Lapis. Please note the Malachite has more of a turquoise color than a green color. It could be another Stone. I don’t know. I’m not an expert. This has been used, may show signs of age or use. Necklace sold separate. Necklace show for styling ideas. Some Pictures are enlarged to show details. Reposh. Purchased then didn’t fit my chain.
