Gold Jewelry Purity Calculations
We have seen a lot of talk about finding inexpensive gold jewelry to sell as “scrap gold”. And of course, we have also heard from people who are intereseted in selling their scrap gold for cash, and want to use the spot gold price as some indication of the value of their jewelry. The K or Karat system may seem confusing, but it is actually fairly simple, so let us give you a quick explanation of the value of gold jewelry as expressed in the spot price of gold.
Now note that you may be unlikely to get an offer of spot price for your spot price since many buyers – refiners, pawn shops, coin shops, or jewelers, need some sort of spread in order to make a profit. But if you are interested in selling, I want you to understand that spot price so you can make a decision about how close an offer is to the true value. If you are buying jewelry for the bullion content, and are not familiar with gold value calculations, this should give you an indication on where you should start making offers too.
Multipliers for gold purity:
24K = .999 = pure
22K = .917
18K = .750
14K = .585
12K = .5
10K = .417
So a 24K gold bullion coins is considered very close to pure gold. An 18K gold necklace is considered 75% gold, or take 18/24 = .75. See how that works? It is easy to understand that 12K gold would be 50 percent gold when you understand that you are starting with 24K gold as a marker for pure gold.
