New Guidelines Clarify: ‘Diamond’ Means ‘Natural’

Leading groups in the diamond and jewelry sectors have collaborated to publish a universal standard to use when referring to natural diamonds and synthetics.

The Diamond Terminology Guideline is a reference on diamond vocabulary for all sector organizations, traders and retailers to use, nine industry bodies said in a joint statement Tuesday.
The document stipulates that the words “diamond” and “gemstone” imply natural origin. The industry should use “synthetic,” “laboratory-grown” or “laboratory-created,” and should avoid the terms “real,” “genuine” and “authentic,” when describing such man-made products.

“Protecting consumer confidence is of paramount importance to the long-term success of our industry,” World Jewellery Confederation (CIBJO) president Gaetano Cavalieri said. “The Diamond Terminology Guideline is an important tool in achieving this, by helping standardize the terminology used to clearly distinguish between diamonds and synthetic diamonds, in all communications, among ourselves and with our customers.”

The guidelines are based on the ISO Standard 18323 for jewelry and on CIBJO’s diamond Blue Book, which are internationally accepted benchmarks in the field.

The parties that created the document, in addition to CIBJO, are: the Antwerp World Diamond Centre (AWDC), the Diamond Producers Association (DPA), the Gem & Jewellery Export Promotion Council (GJEPC), the Israel Diamond Industry (IDI), the International Diamond Manufacturers Association (IDMA), the US Jewelry Council (USJC), the World Diamond Council (WDC) and the World Federation of Diamond Bourses (WFBD).

De Beers Will Start Auctioning Other Mines Goods

De Beers  will begin auctioning rough diamonds from other mining companies to provide a broader range of goods.

The company will pilot the new program this year, making it easier for customers to buy their entire supply in one place, Neil Ventura, De Beers executive vice president of auction sales, said on Monday.

“One message that’s come through from our recent customer engagements is a desire for us to develop our supply offering in certain areas, so that there is a fuller and broader range of material available for purchase,” Ventura said.

“Based on this customer feedback, in 2018 we will be testing the potential to grow our core rough-diamond sales business through making some purchases from third-party sources,” he added.

The diamonds will come from miners which De Beers has carried out due diligence, and will only be a small minority of the goods De Beers offers.

Historic 910 carat, The Fifth Largest Diamond Recovered

Gem Diamonds has recovered a 910 carat rough diamond at its Letšeng mine in Lesotho, the fifth largest rough ever found.

The D colour  type IIa diamond is the largest to be unearthed at Letšeng, outranking the 603 carat Lesotho Promise recovered in 2006.

That stone was sold for $12.4 million, to Graff Diamonds, which owns a 15% stake in Gem Diamonds.

Last year, Graff bought the 1,109 carat Lesedi la Rona, the second largest rough diamond in history, for $53 million, or $47,790 per carat.

The discovery follows a recent revival of exceptionally large stones recovered at Letšeng, which is known for its high value production.

GIA Unveils Plans for Labs in Surat and Antwerp

The Gemological Institute of America (GIA) will this year open a laboratory in Surat, and expand its operations in Antwerp to include diamond grading.
The GIA has secured premises for the two locations, and expects to open both in the second quarter, it said Monday.
The Surat laboratory will bring the GIA’s services — including its Melee Analysis Service for detecting synthetics — closer to companies in that important manufacturing hub, the organization noted. In Antwerp, it will introduce diamond-grading services, and increase capacity for its mine-to-market (M2M) program, which matches rough diamonds to their resulting polished, the lab said.
“Expanding our facility in Antwerp, and opening a new location in Surat, continues GIA’s mission-driven effort to bring our research-based laboratory services for diamonds, colored stones and pearls ever closer to our clients,” said Tom Moses, the GIA’s executive vice president and chief laboratory and research officer.
Clients will be able to drop off goods for every service at both the Surat and Antwerp labs, the GIA added.
