Answer:
Her mother gave old gold jewelry to the goldsmith to polish. The next day when they brought the jewelry back, they found that there was a slight loss in its weight. ... In the jeweler's shop, to polish gold jewelry it is dipped in an acid called Aqua Regia. Aqua Regia dissolves the outer layer of gold.
