The inspection requests concerned more than 12,493 samples of diamonds and other precious and semi-precious stones.

Our participation had three main focuses: the examination of valuable collectables, control and inspection and verification of the accuracy of electronic scales," he said.
Aisha Al Mazrouei, Head of the Gemstones and Precious Metals Unit at the Consumer Materials and Commodities Lab Section, said that the DCL stall at the exhibition contained a mini lab that examined and analysed precious stones and metals on behalf of visitors.
"In addition to that, our trained officials were involved in advising visitors on ways to evaluate the quality of diamonds and the most important points to be taken into account in the purchase of jewellery. They also answered questions from visitors in the field of precious stones and precious metals, who were delighted with the service provided by Dubai Municipality," she said.
