Beautiful natural Malachite is really hard to find; thus the high price of this simple Rivière style necklace. (Synthetic Malachite is abundant, but I don't use synthetics.) Bead shapes will vary, depending on what I can source, but if you love the rich, vibrant green of natural Malachite, focus on that attribute. This should sit about an inch below the collarbone, so I make it about 18" with a lobster clasp and 2-3" extension. If you would also like a bracelet or earrings, they would be single bead designs.
