How to Understand Gold Carat

However, the closest purity that can be found to 24 carat pure gold is gold bullion with a purity of 995/1000 or 999.9/1000. Controlling and knowing the settings of the products produced from alloys of different purities obtained by reducing the purity in order to process gold is essential for the necessary mathematical operations. Manufacturers must write the carat stamp or the gold content in milliams on the inside of the products they produce by reducing the purity of pure gold or in a visible place.

For example ;

22K…..916
21 K….875
18K….750
14K…. 585
8 K….. 333

When we wonder how many carats the product in question has for both the retailer and the end consumer, we come across four alternatives. Stamp Control: Both the retailer and the end consumer can be informed through the stamp control printed on the product by the manufacturers. If the information obtained through this control needs to be confirmed or if the products checked do not bear any stamps, we will have to turn to other alternatives. Control with touchstone and setting water: This method is done in the store by expert jewelers with certain occupational safety measures. The product to be checked is cut due to the possibility of coating, and a line is drawn by rubbing the cut surface against a touchstone, which is a black stone. The number of lines should be equal to the number of our setting waters. A different setting water is applied to each drawn line and waited. While incorrect settings are deleted in a short time, the line in contact with the correct setting water remains intact. This shows us the setting of the product.

Control in the setting house: All products that cannot be obtained by previous methods or in bulk quantities can be melted and their settings can be checked after certain tests in the laboratory environment. This method is the most guaranteed method. Control with special devices. Depending on the development of technology, the purity level of the product is checked with special devices developed for this purpose. However, this method is not very common as it is available in a very limited number of jewelers.
