The Value of Gold in the Jewelry must be calculated based on the entire weight of the jewelry minus the weight of diamonds and gemstones. The cost of diamonds or stones must be added apart from the Gold. Gold jewelry comes in different Karats, which is the unit of measurement of the purity of Gold. 24 Karat gold is the purest, but it is not fit for making jewelry pieces because it is too soft to be molded into any shape and retain that structure.
Alloys such as zinc, copper, or silver are added to enhance the durability of Gold. Mostly you can find 22 Karat gold jewelry in the market. The buyer's price is Gold based on the Karat. More Karat means the Gold is high quality and has a higher purchase price. This helps in determining the gold price for Gold buyers.
