Buying Guide: Key Purchase Considerations
- Stone type: Decide between lab-grown diamonds (real diamond properties) and cubic zirconia or other simulants when on a tighter budget.
- Metal: White gold, yellow gold, and silver each affect color matching with stones and other jewelry. Consider skin-tone and wear frequency.
- Setting style: Four-prong settings maximize light return for sparkle; martini or bezel settings offer different aesthetics and security.
- Carat vs perceived size: A 2.00 cttw stud often looks substantial; pendant may appear larger visually depending on cut and mounting.
- Chain length and layering: For pendants, consider chain length (18 inches common) and compatibility with existing necklaces.
