Gold has been valued and used for jewelry and coins since before recorded history. Men have revered this metal using it for monetary systems and fine jewelry. Here is a link with more information about gold.
The chemical symbol for gold is Au and it's atomic number is 79. Gold melts at 1064.43 °C. When gold is used for jewelry manufacturing it is usually mixed with other metals or alloys to add hardness and wearability.
Alloys can be mixed with gold to effect color, strenght, or percentage of pure gold. The percentage of pure gold effects the retail and your selling price.
Below is a list of common gold alloys used to change the color of gold.
- Green gold (silver, copper)
- Rose gold (copper)
- White gold (nickel, palladium)
Alloys are used in yellow gold to change the percentage of gold, to make it more economical. The alloys used are:
After the alloys are added, these are the percent gold, The Karat System, used for jewelry.
100 % = 1000 fine = 24 karat
91.7 % = 917 fine = 22 karat
75.0 % = 750 fine = 18 karat
58.5 % = 585 fine = 14 karat
41.6 % = 416 fine = 10 karat
When you sell metal that has alloy mixed, to lower the percentage of pure metal, you do not get paid for the alloy. In other words if a piece of jewelry is 10 karat gold, you will be paid for the 41.6% of pure gold and the 59.4% of alloy is melted away. The same goes for the other karat percentages. The only dollars paid for scrap are for the pure gold.
