How is the value of gold per gram calculated? It is useful to understand its value before buying or selling it.
When selling gold, it's helpful to understand its value before reselling it: Here are the steps to calculate gold value per gram before going to a gold buyer. It's helpful to understand the exact value so you can properly define the amount you're getting.
The first step to understanding the value of gold per gram is to determine the carat number of each piece. To do this, it is necessary to find the stamp, a number engraved on the gem and surrounded by a diamond that indicates the amount of gold present in the object. If the figures are illegible, it is advisable to have the gold evaluated by a trusted goldsmith, who will understand through a specific chemical test whether the objects are really gold or just plated.
If there is any doubt about the value of your jewelry, it is possible to acid test it by purchasing a stone made up of materials including novaculite and nitric acid from specialist shops, capable of testing gold at 10, 14, 18 and 22 carats. . To evaluate the object, as is done in a regular gold shop, just rub the stone on its surface and pour a drop of 14 karat acid: if the tested object is actually 14 karat, it will resist the acid and not change. otherwise it will turn brown.
Finally, it is possible to evaluate gold, thanks to the skey test: it is necessary to purchase a gold tester or a checking pen. In this way the tests can be carried out without resorting to nitric acid. To understand the value of jewelry, just draw a half-centimeter line on the object, crossing it four times without removing the tip from the metal. Afterwards, I will draw a line on a white sheet with the same pen: if the line is light brown and green after a few seconds, the gold is below 10 karat;
if the line is light brown, the gold is 10 karat;
if the line is dark brown, the gold is 14 karat;
if the line is orange, the gold is 18 karat;
if the line is yellow, the gold is 22 karat;
if the line is red, the gold is 24 karat.
To understand how to calculate the value of gold per gram, it is therefore necessary to determine the weight of gold in grams. It is important to get a specific scale: it is not the normal scale used for cooking, but a special scale that can be purchased from a jeweler. Items must be weighed in carat groups placed on the scale.
