She admits she is herself a big fan of coloured gems.
"I like coloured stones...Indian girls tend to wear a lot of clear stones, but I think with the Indian skin colour, coloured stones looks beautiful and stunning. So, I think we should delve into getting more coloured stones," Sonam told IANS.
She was in the capital for the first edition of India International Jewellery Week (IIJW).
The actress, who is also the brand ambassador of Gems and Jewellery Export Promotion Council (GJPEC), is fond of jewellery.
She said: "I like to wear modern Indian jewellery as well as traditional Indian jewellery. I just like jewellery in general, I can't select and that's why I think its a perfect brand fit."
Talking about Indian jewellery, Sonam said promoting them internationally can help the country to flourish.
"I think it's a great opportunity for India to promote jewellery internationally everywhere, because we as a country have the potential to grow and make money to help our country flourish," she said.
She started her Bollywood career in 2007 with Sanjay Leela Bhansali's Saawariya opposite Ranbir Kapoor, followed by Delhi-6 in 2009 with Abhishek Bachchan.
