Thank you for your inquiry. I already checked with a jewelry specialist to assess the purity of the 21 carat gold or above. The specialist used a combination of methods to test the gold, including:
Visual inspection: The specialist examined the gold for any signs of discoloration or impurities.
Hallmark test: The specialist looked for a hallmark on the gold, which is a stamp that indicates the purity of the metal.
Acid test: The specialist applied a small amount of acid to the gold to see how it reacted. Pure gold is resistant to acid, so if the gold dissolved, it indicated that it was not pure.
Based on these tests, the jewelry specialist confirmed that the gold is above 21 carat pure.
