Jewelry Buyers Still Desire In-Store Experience


Consumers still prefer speaking with jewelers before making a purchase, despite the recent rise in online purchases, a survey has found.
Some 64% of people who bought jewelry visited a store to consult with an expert while deciding what to buy, according to a study released last week by Jewelers of America (JA). That’s 26% more than for other luxury items, the trade body’s online survey of 2,019 consumers showed.
Consumers who talk to a jeweler during the research process are also more likely to buy from a local store rather than online, the organization added.
“For consumers, seeing is believing, and they still rely on the expertise and knowledge of their jeweler,” said David Bonaparte, CEO of JA. “The jewelry shopping experience is different from other luxury purchases, and even in the rise of e-commerce, customers increasingly prioritize the in-store shopping experience.”
Even so, the brick-and-mortar trade is fearful of the impact of online sellers. In a separate JA survey of 257 of its members, spanning retailers and suppliers, 39% of jewelry retailers considered e-commerce to be their biggest competition.
However, only 34% of retailers surveyed actually have an online sales platform. At the same time, jewelers are working on improving their in-store experience by ensuring they have well-trained sales staff and high-quality customer service, the trade association added.
Jewelry self-purchasing is more popular for precious-metal products, JA found, with 56% of consumers considering gold jewelry to be a good choice as something to buy for oneself. Some 40% put sterling-silver jewelry in this category, while pieces containing diamonds and gemstones were more likely to be a candidate for gifting. Overall, 50% of consumers thought fine jewelry had sentimental value and helped to mark special occasions, JA said.

Rough Demand Stable at $450M De Beers Sight



De Beers reported steady demand for rough diamonds at its December sight as sales showed an increase over the equivalent period last year.

The miner sold $450 million worth of rough in its final sales cycle of the year, including last week’s sight in Gaborone and its auctions, it reported Tuesday.

Provisional proceeds rose 6.6% compared with actual sales for the same period last year, though they slipped 3.4% from November sales.

Debmarine Splashes $142M on Diamond Ship


De Beers is planning to add the world’s largest custom built diamond mining vessel to its fleet at a cost of $142 million.
The ship will be the sixth belonging to Debmarine Namibia, a 50/50 joint venture between the miner and the Republic of Namibia, De Beers said Tuesday. Expected to begin operations in 2021, it will enhance the company’s ability to recover diamonds off the southern African country’s Atlantic coast, the rough producer added.
“There is a great amount of potential in Namibia’s marine diamond deposits, and this new vessel will support our strategy to continue to grow our offshore operations,” said De Beers CEO Bruce Cleaver.
Earlier this year, De Beers launched the MV SS Nujoma, the world’s largest diamond sampling and exploration vessel. Acquiring the new ship will help the company capitalize on that vessel’s work, and support the long-term future of Namibia’s diamond sector, Cleaver added.
Kleven Verft, a Norwegian ship-building company that constructed the Nujoma, will also build the new vessel, and has signed a memorandum of understanding with De Beers.

Synthetic Diamond Fraudulently Inscribed To Match Natural Diamond Report

Improvements in diamond growth technology and methods have led to a noticeable increase in colorless synthetic gem diamonds in recent years. Concerns in the diamond industry focus on laboratory-grown diamonds not being properly disclosed or even being sold as natural stones. Through careful examination and analysis, gemological laboratories can separate natural from synthetic diamonds. Occasionally, however, fraud is involved in attempting to conceal a gem’s identity. The Carlsbad laboratory witnessed such an attempt.
On this occasion, a round brilliant cut (figure 1, left) was submitted for an updated diamond grading report. Its girdle was inscribed with an actual GIA report number issued in 2015 (figure 1, right). The older report was for a natural, untreated diamond and contained the following grading information: 1.74 ct, round brilliant cut, D color, Excellent cut grade, and VVS1 clarity. Upon grading, the new submission was described as a 1.76 ct round brilliant cut with F color, Excellent cut grade, and VS1 clarity. Moreover, our screening processes determined that the newly submitted sample needed additional testing to determine its origin. This examination revealed it to be an HPHT-grown synthetic diamond. Synthetic cuboctahedral growth structure and phosphorescence were clearly visible in DiamondView imaging (figure 2).
DiamondView imaging of synthetic growth structure and blue fluorescence.
Figure 2. DiamondView imaging showed the synthetic growth structure and blue phosphorescence typical of HPHT-grown synthetic diamonds.
Aside from the observed discrepancies in weight (1.74 vs. 1.76 ct), color (D vs. F), and clarity (VVS1 vs. VS1), FTIR spectra clearly showed that these were not the same diamond. The natural diamond from the original report was type Ia with aggregated nitrogen impurities, while the new one was type IIb with boron impurities (figure 3). Careful examination of the report number inscribed on the synthetic diamond revealed a font different from the one used by GIA, proving that it was not an authentic inscription.
FTIR absorption spectra of natural and synthetic diamond.
Figure 3. FTIR absorption spectra revealed that the synthetic diamond was type IIb, whereas the fraudulently inscribed report number referred to a natural type Ia diamond. The spectra are offset for clarity.
While most synthetic diamonds that come to the laboratory are properly disclosed, some are submitted out of concern that a stone presented as natural might be synthetic. Rarely do we encounter the type of blatant fraud described here. It is important for the industry and public to exercise caution, because these types of misleading practices do occur. We believe the submitting client noticed inconsistencies with the GIA report information and sent it to the lab for an updated report. If any doubt exists or some aspect of a diamond (such as an inscription) seems odd, the stone should be sent to a gemological laboratory for verification.

CIBJO and the IDC Agree


The World Jewellery Confederation (CIBJO) and the International Diamond Council (IDC) have decided to use the same terminology for describing diamonds, making it easier for consumers to understand grading.

CIBJO agreed to make amendments to its Diamond Book — a guide to grading standards and terminology — following requests by the IDC, an organization that works to ensure consistency in grading across the industry. The IDC’s language will now be “harmonized” with that of the Diamond Book, CIBJO said Tuesday.

“The true beneficiaries of this agreement are the diamond consumers, who will now be able to refer to a single set of rules for describing diamonds,” said CIBJO president Gaetano Cavalieri.

The two organizations finalized the agreement at the CIBJO Congress in Bangkok this week. The International Diamond Manufacturers Association (IDMA), one of the IDC’s founding bodies, has also endorsed the new Diamond Book.

Diamond fluorescence

There is common misconception that a diamond exhibiting fluorescence under ultra violet light has some kind of colour defect or transparency issue.

This NOT true at all. The naturally occurring fluorescence phenomenon is a unique completely hidden feature, which is present to some level in approximately 30% of all diamonds.

The effect is seen in Diamonds which have Carbon bonds which include boron.

Boron causes the diamond to glow when held under a powerful ultra violet light also known as blacklight.

The amount of boron in the Carbon bond making up the diamond will determine the level of fluorescence.  Fluorescence is rated by the Laboratory as Very Strong, Strong, Medium, Faint, None. This relates to the strength of the fluorescent glow under ultra violet light.

Victor Mine To Be Closed By De Beers in 2019


 
Production will cease at the De Beers Victor mine in Canada in 2019, the company announced Wednesday. 

The Diamond Mine in Ontario started production in July 2008 will continue to operate until the open pit is exhausted. This is in line with the company’s original study of mine and the plan for the project.
The mine has yielded 7 million carats of rough exceeding the forecast of 6 million carats predicted for its life of mine.

De Beers discovered the Victor kimberlite cluster in 1987 the first economically viable mine in Canada.
