"As we announce our financial performance, we remain steadfast in our execution of three key initiatives in 2014,” Blue Nile president and CEO, Harvey Kanter, said.
"These include enhancing the user experience, developing our product lines in bridal and diamond jewellery, as well as fashion pieces through the Designer Collective, and expanding internationally by building our presence in China and growing our established markets."
The internet-only retailer launched its Designer Collective in March this year. The offering includes a collection of rings, earrings, pendants and bracelets designed by “established designers and emerging talent”.
The 2014 first quarter figures follow strong results for the company in the fiscal year ended 29 December 2013, where a 12.5 per cent increase in net sales was reported.
