>Gold is a yellow, noble metal
Because gold is ductile and malleable in it's pure form, it must be alloyed with various other metals to harden it and in some cases, change it's color. The metals used in the alloying process include silver, copper, nickel, zinc, tin and manganese.
For gold, karat grade is used to express the proportion of gold in an alloy or the quality of a gold alloy. Fine gold (pure) is 24 karat. The proportions in other karat are listed in the table below. All jewelry is required by law to be stamped so consumers will know the quality of gold used. Jewelry made in North America is typically marked with the karat grade (10K, 14K, etc.), and jewelry made in Italy is typically marked with the "fineness" such as (417, 583, etc.). So if your jewelry does not have a karat grade stamped on it, check for a 3-digit fineness number.
Cleaning your gold jewelry
Gold will develop a film build up of oils from lotions, powders, soaps, and natural skin oils which takes away from it's beauty. Chemicals in the air can slightly oxidize the gold depending on the karat grade used. Don't let your gold jewelry come in contact with chlorine bleach when you are doing household chores because it can damage jewelry over time. A little time and effort on your part will keep your jewelry looking new like the day you first wore it. We've listed four ways to clean your gold jewelry.
1. Detergent Bath
2. The Cold Water Soak
3. The Quick-Dip Method
4. The Ultrasonic Cleaner
