Gemvara and Online Jewelers Hold Strong Over Tiffany & Co.

One of the surest signs that online retail is taking over?  The new predominance of online fine jewelry sites.  Start-ups like Gemvara (one of our favorites) and more established players, like Blue Nile, are holding strong, while the rest of the fine jewelry sector actually slows down.  Tiffany & Co., for instance, just lowered its share outlook for the year.
