Raw Amethyst Necklace

This minimalist amethyst necklace is a lovely ode to the variety and beauty of earth's crystals. Amethyst is a purple-colored quartz, and was once considered to be in the same category as diamonds, sapphires, rubies, and emeralds. It has a chemical composition of SiO2, a trigonal crystal system, and (among other ways) it obtains its color from substitution by irradiation of trivalent iron Fe3+ for silicon. Each necklace is unique, incorporating a raw amethyst crystal into an 18 inch sterling silver chain. Exact shapes vary, but each is beautiful and likely to become a cherished favorite. Perfect for: Rock lovers Geologists Earth scientists Anyone enthusiastic about mineralogy and the vast beauty within our planet's composition
