Which gemstone necklace styles are most popular?
Topaz and amethyst necklaces lead the list. Swiss Blue and London Blue topaz pendants come first, followed by amethyst in round, cushion, oval and pear shapes. Peridot, garnet, smoky quartz and citrine in sterling silver round out the favorites.
What affects the price of gemstone necklaces?
Stone type, size and metal drive the price. Carat weight, whether diamond accents are added, sterling silver versus stainless steel, and chain length all play a part. Use the Price filter on this page to set a budget.
Are the gemstones natural or lab-created, and are they treated?
Natural stones are the focus, with some exceptions. The page features natural gemstones, though a few pieces use simulated stones such as simulated turquoise, so check each listing. In general, many topaz stones are color-enhanced and amethyst is sometimes heated.
How do I choose between topaz, amethyst and peridot?
Pick the color you wear most. Topaz offers cool blues, amethyst gives soft purple, and peridot adds fresh green. Garnet and citrine bring deep red and warm yellow if you prefer richer tones against sterling silver.
How should I care for a gemstone necklace?
Wipe it gently and store it separately. Use a soft cloth after wearing, and keep it away from perfume and harsh cleaners. Soft stones like turquoise and pearl need extra care. See our jewelry care tips.
