Gold holds an impeccable value in terms of quantifying one’s wealth as well as for investment. Thus, judging the quality and purity of gold is of utmost importance, both for buyers and for traders.
Primarily, the gold’s purity is determined through the Karat system that measures the same on a scale from 0 to 24. For instance, a 24 karats gold jewellery contains 100% gold. On the other hand, in a 14K gold jewellery, the percentage of gold is 58.33%, and the rest is other metal or alloy.
The gold purity can be measured both by percentage and parts per thousand. However, to convert the Karat into a percentage, one needs to divide the Karat number by 24 and then multiply it by 100.
Another easy way to determine gold’s purity is by checking the hallmark stamp on gold jewellery. This hallmark includes the authorised logo, date of manufacturing, carat weight or fineness of the gold in question. In several countries, including India, it is mandatory to sell gold jewellery with hallmark stamp.
Lastly, the traders generally use an electronic gold tester to measure the quality and purity of gold. It shows the result accurately within seconds.
