00:00We are doing a story on why Dubai is called the city of gold. As you know people from all over
00:07the world come to the emirate to buy gold because they trust the gold that they buy from the city.
00:15They trust its purity and we are here at Dubai municipality to find out just why the gold that
00:23you buy here in Dubai can be trusted. We will be making random inspections along with Dubai
00:30municipality inspectors. They will be making random checks at jewelry stores across Dubai
00:36and we are traveling with them to see the entire process on how they pick jewelry pieces from
00:46jewelry stores and bring it to the Dubai municipality lab to test for its purity.
00:51We have nine inspectors just we are controlling the product in the emirate of Dubai.
01:00For the gold and jewelry we have four inspectors. They are visiting the market every day as
01:09the daily program what we have we are issuing them through the system. For the beginning
01:15after getting the daily program they will see where it is located. We make the program
01:26it is very simple through the system. They will choose the shop through the
01:36grouping. Grouping it means most of the shops should be close to each other to make it easy
01:43for the inspector to cover most of them. I have to add the inspector's name. For example my name
01:53Maryam and the date for today okay and this is I click here they will show for me that this is
02:02group number 21 have three shops okay the shops in Al-Mazaya center. When they will
02:12enter to the to the shop they will check the the trade license and the name and they will check on
02:20the shop so many things if they have different different items like a bangle, chain, ring,
02:29bracelet they will they will check it as randomly as per the procedure they will collect it
02:35in front of them and they will check the mark. I will check the license number the same number
