One of the machines identifying all lab-grown diamonds was the Sherlock Holmes machine by Yehuda, which sells for about $6,500.

The De Beers DiamondView identified 100 percent of lab-grown diamonds. It sells for about $35,000.

The Presidium Synthetic Diamond Screener II identied all lab-grown diamonds. But the machine, which sells for $600, had a false-positive rate of nearly 16 percent. It “works by screening out type IIa colorless diamonds, as those are likely to be synthetic, rather than actually identifying lab-growns,” according to Rapaport.

The sample was described as “deliberately challenging.”

Several other models referred all lab-grown diamonds for additional testing, Rapaport explains. This group, which is not designed to detected lab-growns conclusively, included:

  • De Beers’ SYNTHdetect ($17,000).
  • De Beers’ DiamondSure ($18,200).
  • Gemological Institute of America’s iD100 ($4,995).
  • HRD Antwerp’s M-Screen+ ($63,000).

Through the Assure Directory, trade participants can access objective and third-party-verified information on the relative performance of Diamond Verification Instruments and guidance on how to ensure that their business is protected from undisclosed laboratory-grown diamonds.

Jewelry and accessories retailer Charming Charlie may have gone bankrupt and closed its 261 stores, but you can expect to see the brand resurface in coming months.

Charlie Chanaratsopon, founder of the company, is acquiring its trademarks, internet properties and other intellectual property for about $1.23 million, the Houston Chronicle reports. He was approved to buy the assets following a bankruptcy auction.

He plans to revive Charming Charlie as primarily an online brand. It will have only a few permanent brick-and-mortar stores, which will open early next year.

The company’s main advantage is its 10-million-strong customer base, said Chanaratsopon, former CEO of Charming Charlie.

The company said in July that it was closing all of its stores in connection with its Chapter 11 bankruptcy filed July 11.

A San Diego woman woke up without her engagement ring, and she immediately remembered a dream she’d had the night before.

One where she’d swallowed her engagement ring.

Jenna Evans immediately told her fiance, Bob Howell, and they headed to urgent care. She told the story in a Facebook post that has gone viral, garnering 62,000 shares as of Sept. 16.

She ended up seeing a gastroenterologist, who performed an upper endoscopy.

“Everything went great, they found my ring just beyond my stomach in my intestines, retrieved it and gave it to Bobby, not me,” she wrote.

She also divulged a bit about the dream that got her into the predicament.

“I was having a dream that Bobby and I were in a very sketchy situation involving a high speed train and bad guys (I have very exciting and vivid dreams) and he told me I had to swallow my ring to protect it; so I popped that sucker off, put it in my mouth and swallowed it with a glass of water riiiight about the time I realized what I was doing,” she explained. “I assumed this too was a dream, because WHO ACTUALLY SWALLOWS THEIR ENGAGEMENT RING, so I went back to sleep.”

The ring was made by Simone Jewelry Designs in Houston. CBS8 reports that it includes a 2.4 carat diamond.
