NEW YORK (TheStreet) -- Fear of a slowing housing market may be weighing on investor confidence but consumers haven't stopped buying jewelry, according to TheStreet's Debra Borchardt.

Tiffany & Co. ( TIF) reported strong earnings results and raised its full-year sales forecast. The company brushed away fears of a softening China by posting stronger-than-expected sales and even saw an 11% increase in European sales, Borchardt said. Overall, global revenue rose 4.4% to $925.9 million.

Lower metal prices coupled with higher sale prices were enough to fuel investor optimism, and the company plans to open three new stores, in Mexico, Italy and China.

Movado Group ( MOV) also reported strong earnings, with a 17% jump in sales and a 59% increase in operating income. Borchardt added that the company increased its fiscal 2014 guidance and expects sales to increase 13%.

Signet Jewelers ( SIG) reports earnings on Thursday and should also benefit from lower input costs, she said. Zale Corp. ( ZLC) will report on Wednesday. Borchardt noted that there is an upward bias for the stock, with heavy trading in the call options.
