MoCI has stated that customers are topic to different types of cheating and fraud by some traders and that the actions have been taken in view of growing entry of low-cost and imitation stones in the industry.
Implementing provisions of Royal Decree 109/2000, MoCI examined 978 samples of valuable stones in 2017. It had examined 377 samples in 2016.
Nasser bin Ashraf al Baloushi, head of valuable stones division and testing laboratory in the Directorate General of Standards and Metrology, MoCI stated, “Article 7 of Royal Decree 109/2000 states that it is not permissible to sell valuable stones unless they are accompanied by a card indicating the name of the stone, its class, weight, colour and quality in terms of purity, properties, safety from breaking, scratching and any other defects and the extent of exposure to any kind of treatments or processing.”
Baloushi stated that a specialised lab will figure out the sort of remedy for these stones, if any, and concern a certificate bearing the specifications. “The test will be for polished stones, diamonds and pearls. Jewellery items which have precious as well as raw and rough stones will also be tested.”
MoCI’s directorate is attempting to boost the level of awareness amongst traders and customers and coordinating with government and private agencies.
Baloushi stated that all-natural stone remains a all-natural a single regardless of its geographic origin. “However, it is the geographic supply which determines the cost. Collectors of valuable stones usually attache large significance to their geographical origin or nation of origin, which has the greatest influence on cost. The dominant culture from exactly where the valuable stone is imported has its influence on their demand. For instance the jade stone was pointed out by Xu Shen (about 58-147 AD) in the initial Chinese dictionary as a symbol of beauty. Jade has a lengthy history in Chinese civilisation. A quantity of archaeologists discovered that some pieces produced of jade dated back to about 5000 BC. This is why jade stones in China are costlier than emeralds.
“The best example of influence of the source is Iranian turquoise whose traders often import turquoise from Tibet in China. They sell it in their markets as Iranian Turquoise, perhaps because of the historical background of the stone. There are other examples too. Australian opal is higher than the Ethiopian opal which makes Ethiopian opal traders export it to Australia and then re-export it to the rest of the world.”
Earlier, there was no approach to figure out the supply nation of coloured valuable stones and diamonds. The geographical origin of gems or diamonds was primarily based on their high quality and look as nicely as their colour. For instance, the really vibrant red sapphire was referred to as Burmese, even if it was not its supply. “The identification and determination of origin is done using modern high-tech devices. There are some devices and techniques used by some of the world’s top laboratories, including optical analysis by microscope, spectroscopy in ultraviolet rays visible near infrared rays.”
Baloushi stated that it was tough to figure out the nation of origin since of continuous emergence of new exporting nations and the higher expense of these technologies. “For example, the Gemological Institute of America (GIA) mentions the country of origin in test reports of stones: red sapphires and emeralds. GIA is able to identify the source country in all cases.”
He urged customers to purchase valuable stones from shops specialised in promoting them. “These specialised shops are inspected regularly by experts from the directorate. We urge consumers to take official invoice which has the name of the stone and all other basic information. The invoice will help in protecting the right of the buyer. Also ensure that the card is attached to the stone as stipulated in Article 7 of Royal Decree 109/2000 which ensures it has been tested in a specialised laboratory.”
