Choosing diamond necklaces

Check the chain or necklace length, pendant dimensions and clasp information in each listing. Consider where it will sit on your neckline and how it will layer with jewelry you already own. A pendant image alone does not establish that a chain is included.

Know your gemstone

Read each listing for diamond origin, stone measurements and any grading documentation. Natural and laboratory-grown diamonds are both diamond, but origin should be disclosed; never infer it from price alone.
