Vintage Graduated Genuine Malachite Stone Beaded Necklace Approximately 22 inches long Brass barrel clasp with oxidation Glass seed bead spacers Preowned Great condition with minor wear Malachite forms in caves or caverns as stalactites or mineral deposits filling the cracks or fractures of rocks. Fluids containing dissolved minerals seep out of the earth, tricking down rocks walls through fractures and cracks or dripping off of cavern ceilings leave behind copper-rich mineral deposits of malachite material. Over time the water's composition changes resulting in a change of color in the deposited minerals left behind. That process is responsible for the varying shades of malachite green rings. Malachite is a rare and sought-after mineral. Mining and cutting of malachite is a labor-intensive task; therefore, it comes at a high price. If you find a product listing that says something like "Genuine Natural Green Malachite, Grade AAA, 100% Natural" with a price that seems too good to be true, then it probably is a fake. Even low-quality malachite will come at a cost. Imitation malachite with genuine claims, unfortunately, is a common occurrence, particularly in online marketplaces.
