Over the past month, prices for certified diamonds have fallen. Margins of profit in the production of diamonds remained under pressure, as trade in diamonds slowed during the calm season, prices sagged, but prices for rough diamonds remained at a high level, Rapaport said in a press release.
The price index for diamonds RapNet Diamond Index (RAPI) for stones weighing 1 carat decreased during the reporting month by 2.4%. RAPI with respect to certified diamonds weighing 0.30 carats fell by 1.3%, and diamonds weighing 0.50 carats slightly increased by 0.3%. RAPI for diamonds weighing 3 carats fell in July by 0.5%.
As the July Rapaport report called Sluggish Trading says, in the US and the Far East, there is a strong demand for commercial grade diamonds weighing less than 1 carat in the SI-I2 purity range and GM color.
There is a high demand for diamonds weighing 0.3-05 carats GM, purity VS2-I2, and there was a deficit in this category of products on the market. Many New York and Antwerp dealers in July went on vacation, which determined a further reduction in trade turnover. Some Indian diamond manufacturers have lowered prices for 1-carat diamonds due to low demand, overstocking of this market segment and the need to ensure the inflow of cash.
The results of the Indian International Jewelery Show (IIJS) were quite weak for diamond suppliers, but there is evidence of stability in India's domestic demand for jewelry and improving sentiment ahead of the October season of Diwali. Limited liquidity and the desire of buyers to purchase polished diamonds for the fulfillment of orders received, rather than replenishment of stocks, is noted.
While the trade in diamonds was slow, the rough diamond market in July was quite active. Diamonds supplied by mining companies went up about 2%, and this product was sold in the secondary market with premiums around 5%. Diamond manufacturers purchase raw materials to replenish the diamond reserves for the Diwali holiday.
Suppliers of diamonds hope for a rise in prices during the festive season, sufficient to justify the purchase of expensive raw materials. At the same time, buyers are expected to remain cautious, at least until the Hong Kong Jewelry Fair, which will take place from September 15 to 21, and revive the market in anticipation of the holiday shopping season in the 4th quarter.

A purple-pink diamond weighing 8.41 carats was sold at a record price of $ 17.8 million for this category at Sotheby's auction in Hong Kong, nationaljeweler.com reports.
The maximum pre-auction estimate of the stone was $ 15.5 million. A
pear-shaped diamond of impeccable purity, a fantastically bright purple-pink color, was made in New York from a 19.54 carat diamond mined by De Beers. The degree of its purity is considered very rare for pink stones, and the color characteristics received the highest rating of the Gemological Institute of America (GIA).
The diamond was purchased by an unnamed private buyer from one of the Asian countries.
Prior to this, the record belonged to a fantasy purple-pink diamond weighing 5 carats - it was sold for $ 10.8 million in November 2009, also in Hong Kong.
In general, the autumn auction of "Magnificent Jewels and Jadeite Autumn Sale" in Hong Kong raised $ 75.2 million, which is 67% of the potential value of all exhibited goods.
During the trades 69% of lots were sold (234 out of 339).

One of the claims, in which the retailer from Nashville Genesis Diamonds was accused of selling diamonds certified by the gemmological laboratory of EGL International with overstated quality characteristics, was settled. Thus, in relation to the company, three other proceedings remain open, nationaljeweler.com reports.
The settled proceedings were opened after the request of the customer Genesis Diamonds, which purchased from the retailer a diamond of 2.06 carats. According to the certificate of the EGL International laboratory, the color of the stone was categorized as G, and the purity of the stone was assigned to VS2. However, according to experts of the Gemological Institute of America (Gemological Institute of America), the stone was of lower quality - J and SI2 respectively - and therefore cost twice cheaper than it was purchased by the buyer.
Attorney Eli Richardson (Eli Richardson), representing the interests of the retailer, said that the proceedings were closed on terms that "satisfied both sides."
He added that the claims were groundless, valuation of diamonds - a subjective process, and the plaintiff acquired a stone at a fair price.
The leading international professional diamond trade network, RapNet, decided to exclude from its database the stones evaluated by the gemological laboratories of EGL International. The reason for the decision were reports that laboratory experts overestimate such indicators of stone quality as color and purity.

Correction of prices for diamonds and diamonds would be a positive development for the Indian diamond industry, which is currently experiencing a liquidity crisis.
In addition to reducing opportunities to raise funds, price correction is also facilitated by the market's overstocking, which will soon cease operation for almost a month due to the beginning of the annual Diwali holiday on October 20.
"The prices for diamonds and diamonds are likely to decline by 5% -10% amid a decline in demand and a trend towards an increase in supply." The demand for diamonds in world markets is also low, so Indian diamantaires are waiting for difficult times, especially in the short term. we hope that the holiday season, which lasts until December, can contribute to some increase in export orders, "said Vipu Shah, chairman of the Gems and Jewelery Export Promotion Council (GJEPC) l Shah).
In his view, the liquidity crisis that has started, which is detrimental in the short term, may in the future strengthen the Indian diamond industry, as natural selection will take place during the crisis, which will result in weak players leaving the market.
In addition, Shah said, the crisis will make diamantaires more disciplined in matters of maintaining and managing stocks of products.

In a recent review by the World Gold Council (WGC) of the prospects for the development of the Vision 2020 industry, there is a need to promote "golden" tourism in India to demonstrate to foreigners all the wealth of the assortment of handcrafted jewelry produced in the country in such "gold" centers, as Kolkatta, Jaipur, Ahmedabad, Surat and Coimbatore (Kovai).
WGC's proposal to create a "golden" tourist route in India is fervently supported by local jewelers, who expect it to increase the production of handmade gold jewelry, which is in demand both among foreigners and local residents.
Artisanal jewelry production not only allows buyers to purchase goods for more attractive prices compared to factory products, but also promotes employment growth.
"Our review of the prospects for the development of the Vision 2020 industry presupposes the transformation of the country into a world-class jewelry manufacturer by increasing the export of jewelry by fivefold and doubling the number of workers engaged in this sector." To meet these challenges, handicraft manufacturers need to upgrade their skills, "said the Managing Director of WGC in India Somasundaram PR (Somasundaram PR).
WGC believes that in the next five years, India should try to increase gold jewelry exports fivefold, to $ 40 billion from the current $ 8 billion.

To protect the interests of the end user, the Bureau of Indian Standards (BIS) has initiated the initiative to provide buyers with the opportunity to test a sample of jewelry in the local branches of the organization.
In the framework of the initiative, if the purity of the metal does not correspond to that indicated by the jeweler, the Assaying and Hallmarking (A & H) Center, in which the purity of gold was determined, will be obliged to reimburse the cost of the examined and tested jewelry at three times the size.
The procedure for checking gold starts with the fact that the consumer brings decorations to the center of BIS, where the employee extracts samples from them for carrying out a test with a mass of 0.25 grams. The result of the study will be ready in seven or eight days.
In case the purity of the metal corresponds to the declared, the sample will be returned to the consumer with the appropriate certificate. If the gold turns out to be not the same sample that is indicated in the accompanying documents, a corresponding notification will be sent to the staging assay center demanding payment of a fine. If the assay center repeats its mistakes, in each subsequent case the amounts of compensation for the victims will increase.
The population of India is poorly informed about the branding, and the need to determine the purity of the metal is obvious, especially given that many buyers make transactions based on a trusting relationship with the jeweler, not paying much attention to the reliability of assay stamps.
