Concern about reported suspicions that traders have distributed close to 500 high-quality, treated polished diamonds in the Israeli diamond trade without disclosure

The Israel Diamond Exchange quotes continuing tensions in the region as chief reason.

A natural vivid blue unique heart shape diamond, weighing 1.93 carat, is one of the show pieces at the auction of exclusive gems and jewelry organized by Tzoffey's 1818 to be held during the inaugural US/International Diamond Week at the Israel Diamond Exchange (IDE), March 17-20.

First-ever US/International Diamond Week takes place next month on the trading floor of the Israel Diamond Exchange (IDE).
