Weekly Digest: Alrosa’s Diamond Inspector, Fred Leighton jewels and an 8ct pink diamond treasure

29/03/2018

In a busy week of headlines from the international diamond and diamond jewellery trades, Alrosa fights back against unscrupulous suppliers, Christie’s presents JAR masterpieces at auction and Sotheby’s celebrates the career and personal collection of the late jeweller, Fred Leighton.

ALROSA launches device to identify natural and synthetic diamonds

Russian mining giant ALROSA has introduced its Diamond Inspector – a commercial device for the identification of natural and synthetic polished diamonds.

“The company expects that its relatively low price and high accuracy will allow the detector to be in demand both in Russia and abroad,” ALROSA said in a statement.

“It will help fight unscrupulous suppliers who mix synthetic stones grown in the laboratory with diamonds of natural origin.”
The device has been developed by ALROSA together with specialists from the Federal State Budgetary Institution Technological Institute for Superhard and Novel Carbon Materials (TISNCM). A joint venture, Diamond Scientific and Technological Center LLC, will be in charge of its production and sale.

The ALROSA Diamond Inspector - priced at USD $9,900 - can identify natural polished diamonds, polished diamonds manufactured from synthetic and treated diamonds, and non-diamond imitations (simulants), such as cubic zirconia, moissanite, and others.

The device can analyse both individual diamonds and diamonds in jewellery.

The New York-born jeweller, who died last year, collected pieces not just for their intrinsic value, but for their artistry, rarity and history, the auction house said.

Leighton ran an estate-jewellery business that supplied celebrities on the red carpet, including Nicole Kidman and Kate Winslet.

The Jeweler’s Eye’ collection will be available for public viewing from April 13 to 18.

In particular, the new version of the Guidelines takes account of the Responsible Jewellery Council (RJC) Code of Practices.

The guidelines for the prevention and minimising of adverse environmental impact and environmental risk management have been expanded following the recommendations of the London-based RJC.

The new provisions of the document urge ALROSA ALLIANCE members to state the origin of rough diamonds acquired from ALROSA, possibly emphasizing their Russian, natural and non-conflict origin, and also that they are produced in full compliance with responsible business practices.

RJC will be giving a seminar on its activities at CARAT+.
