💡 Tips for the Perfect Fit

  • Measure your finger at the end of the day when it’s at its largest.
  • Avoid measuring when your hands are cold, as fingers may be smaller.
  • If you’re between two sizes, we recommend choosing the larger size for comfort.
  • Remember, wider rings may feel tighter — so size up if needed.

✨ With the right size, your Shine by Diyanah ring will fit beautifully and comfortably.
