How to Choose a Tennis Necklace
| Factor | What to Explain |
|---|---|
| Carat weight | Higher CTW creates a bolder, more dramatic necklace. |
| Necklace length | Common lengths like 14", 16", 18" and how they sit on the neckline. |
| Diamond size graduation | Graduated tennis necklaces create a more dramatic centre-focused look. |
| Setting style | Prong settings maximize sparkle; bezel accents add a sleek, modern look. |
| Metal colour | White gold feels classic, yellow gold feels warm, rose gold feels romantic. |
| Clasp/security | Secure clasps and safety features if included. |
| Styling | Whether the necklace is best worn alone or layered with pendants/chains. |
