The website www.witengold.com has elegant day wear, gemstones, work wear and diamond jewellery designed by Tamannah.
The collection features rings, earrings and pendants.
"I'm very happy that I'm going to bring out (jewellery) for my fans, who enjoy the element of style in me in my films," Tamannaah had told IANS earlier.
Asked what pulled her into the jewellery designing business, she said: "My father has been in the jewellery business for many years and I have always watched him and spent time with him.
"I always feel that lucky are those people who get a chance to take their passion as profession and turn into something more. I was lucky twice, I got that first with acting and I am doing it again now with jewellery," she said.
