I see many posts approximately buying and promoting gold earrings, 14k and many others and that they listing the load in grams. I apprehend shopping for and selling gold bullion and its relation to the gold spot rate. What’s the address gold chains for example? Does it go with the aid of carats and they by using weight? Is 1 gram of gold earrings really worth similar to 1 gram of bullion? thank you for any insight.
