Now there is a way to identify the amount of gold in rings, bracelets, pendants, necklaces, and chains. Karat is a unit of measurement especially assigned for gold to tell how much gold it contains. A karat is actually a proportion and not the actual weight or mass of gold. It tells you how much of a piece is gold. To put it straightforwardly, a one-karat gold piece has 1/24 of it as gold. As you know, gold jewelry is available as 8, 9, 10, 12, 14, 18, 20, 22, and 24 karat pieces. An 8 karat gold contains 1/3 gold while a 24 karat piece is pure gold.

An acid test kit is available as gold test kits which consist of different vials of acid solutions, a touchstone, and gold needles. There may be up to six vials of acids for testing 10k, 12k, 14k, 18k, 20k, and 24k gold although there may be variations from manufacturer to manufacturer. Gold testing acid is usually a strong acid, such as nitric acid or hydrochloric acid. That is why you have to be careful in using the acid because it can irritate or burn the skin. Some manufacturers of gold test kits provide safety gloves. You can buy your own gloves if they are not included in the kit. Anyway, you may find a touchstone in the kit and it comes handy, especially considering you don’t want to pour the acid on your test object.
