Buying Guide
- Length and fit: A 20 inch chain sits just below the collarbone on most adults. Consider your neck size and preferred neckline when choosing length; some buyers prefer a 16–18 inch for chokers or 20–24 inches for a looser drape.
- Material and hypoallergenicity: Sterling silver is common and cast for all-day wear; verify if you have sensitive skin or metal allergies. Look for nickel-free and lead-free construction.
- Chain style and wear: Singapore and Box chains offer smooth wear with less snagging, while Cuban and Figaro chains provide a bolder look. Think about layering with other necklaces or pendants.
- Finish and durability: Diamond-cut finishes enhance sparkle but may require occasional cleaning to maintain luster. If you wear the chain daily, consider a tarnish-resistant finish and quality clasps.
- Clasp type: A lobster claw clasp is common and easy to use; ensure it is secure to prevent loss.
- Care and maintenance: Clean with a soft cloth and mild jewelry cleaner; store separately to avoid scratches and tangling.

Yes, if it is nickel-free and properly finished; look for hypoallergenic options and verify plating if present.
Can I wear a diamond-cut chain daily?
Yes, but routine cleaning helps maintain shine and prevent tarnish on silver components.
How do I measure the correct length?
