Measure at home with a ring sizer or a paper strip, then compare with the size chart. Measure when your hands are at a normal temperature.

Yellow gold feels warm, white gold and platinum feel cool, and rose gold sits between the two. Choose the metal that matches the jewelry already worn most often.

Check the product page for origin and grading information. Both natural and lab-grown diamonds share the same physical properties.
