Is the Ashley Madison hack sparking a jewelry boom?

It's been a tough week for Wall Street, but there is a silver lining.

Jon Najarian pointed out that Signet Jewelers has seen a spike in the last five days of trade, rising 1.05 percent. Similarly, online bling purveyor Blue Nile, while down 1.05 percent Friday, soared on Wednesday and Thursday this week.

Coincidence? Maybe, not.

The jewelers may need to thank Ashley Madison's hackers, who dumped millions of email addresses and credit card details online this week. Ashley Madison promised anonymity and specialized in enabling infidelity. Two other Avid Life Media hook-up sites, Cougar Life and Established Men, were also hacked.

Victims of the hack are in hot water and could be trying to smooth things over with their significant others in the form of something sparkly.

While Signet and Blue Nile both experienced spikes, not everyone is reaping the benefits; Tiffany & Co shares fell 3.28 percent this week.

Hackers who stole customer information from the cheating site dumped 9.7 gigabytes of data to the dark web on Tuesday fulfilling a threat to release sensitive information including account details, log-ins and credit card details, if Avid Life Media, the owner of the website didn't take Ashley offline permanently.

In all seriousness, several businesses have advertised special deals for the victims of the Ashley Madison breach. Opulent Jewelers posted a promotion on its site on Thursday, offering $500 off purchases of more than $10,000.

Last month, a Reddit user posted a photo, attributed to floral delivery service 1-800-Flowers, advertising an entire field of flowers called "The Ashley Madison."

"The most shocking part was we actually sold an item worth just over $15,000 to a gentlemen from the West Coast of the U.S. right after dinnertime last night," an Opulent spokesman told CNBC. "Our promo code was used, although we don't know if he was just a regular shopper who took advantage of a deal or he was truly an Ashley Madison victim."

1-800 Flowers did not immediately respond to request for comment.
