well in 'Bhatias' ( Indian Sindhi subcaste ).. they wear nathani's outside their own wedding as well. Like if they are attending some one else's wedding all the females guests will wear a small to medium sized diamond nathani. I have seen this a lot here in Bahrain and Dubai.

And oh my wot diamonds. But Bhatia's / Sindhis ( the Indian ones ) are known to wear strictly diamonds and pearls.

Like every year when we go to the temple of Janmashtami ( Lord Krishna's birthday ), the Bhatia ladies are decked in HUGE diamond earrings and nathani's / or solitaire nose pins. My friends mom she wears a two carat solitaire nose pin on her nose daily. Phew. My nose pin is only .35 cent. But VVS1.
