I believe that’s a ‘larin’ (plural lari) of a type used as currency and in trade in areas around the Persian Gulf and Arabian Sea and with trading partners elsewhere. The name derives from the Persian town of Lari, believed to be the first to produce these items.
Early items were generally produced in gold as far back as the 12th Century, but silver larin coinage originating in the Persian Gulf (but also produced elsewhere) was used extensively during the 16th and 17th Centuries, including by trading partners in India, Ceylon, Portugal, Spain and the Netherlands. It's usually in the form of a silver rod, flattened and folded into a hairpin-like shape. A 17th century larin should weigh about 4.75 grams and was rated at 5.5 lari to the Spanish colonial ‘piece of eight’. Smaller ones exist (you say yours weighs 1 gram) with different exchange rates.
Usually, they have an inscription in Arabic, Persian or other languages that relate to where they were produced and giving the name of the local ruler, but it would need an expert to decipher yours. European 'imitations' used for trade usually have some kind of 'squiggly' but meaningless inscription intended to resemble an Arabic language.
