It was a school break. Dani and her family went to Camarines Norte to visit their relatives. The province is known for huge gold deposit. Dani was excited! Her cousins promised to take her to one of the gold mines. She couldn't wait to see natural gold!
But one day while taking fresh bath in a river, she saw a yellow nugget underwater. She thought of it as gold. Dani couldn't believe she would have gold in her hand even before the trip to the mine! She picked up the nugget to examine it later.
Upon reaching the house, Dani immediately rubbed the yellow nugget against a broken porcelain plate she found in the backyard. She discovered that it gives a greenish-black mark. She got a glass and then rubbed it against the nugget. The nugget scratch the glass. Dani started thinking. Was it gold or not?
