The amount of gold jewelry and other products is measured in karats (K),?
The amount of gold jewelry and other products is measured in karats (K), where 24K represents pure gold. The mark 14K on a chain indicates that the ratio between the mass of the gold in the chain and the mass of the chain is 14 : 24. If a gold ring is marked 18K and it weighs 0.4 oz, what is the value of the gold in the ring if pure gold is valued at $300 per oz?
The ring is 18/24 gold or 75% gold.
If the ring weighs 0.4 oz and 75% of that is gold, 0.3 oz is gold.
So, at $300.00 for 1 oz of gold you have $90.00 worth of gold.
BUT! If you are trying to sell the ring, the best a dealer would give is only about $81.00 at the most. The current price is about $900.00/oz.
