Despre Karate la Aur

When shoping gold jewelry, don't forget to look for the karat mark. All some other things being equal, the higher the karat, a lot more costly the piece is.

In America, 14-karat gold, or 583 parts pure gold, is one of typical degree of fineness.

Nothing below 10 karats can legally be marked or sold as gold jewelry in the U.S. Nevertheless, lower karatages, like 8-karat gold as well as 9-karat gold, tend to be favorite in some other countries.

18-karat gold is 18/24ths, or three-quarters pure gold, and jewelry with this fineness is marked 18k or 750, the European designation meaning 75% gold.

Generally look for that karat mark or "k" which appears on the rear of the piece. By U.S. law, in case a karat mark appears it's also advisable to see the maker's brand to make sure the fact that the karat marking is precise. The country of source also needs to appear.

Besides the karat mark, each item of gold jewelry needs to be stamped by using a hallmark or trademark of its producer, and oftentimes its country of origin.

These designations guarantee you that you're purchasing real karat gold jewelry. Weightier pieces include more gold.

Gold Filled, also known as Gold Overlay, describes a layer with a minimum of 10-karat gold that was completely bonded by pressure and heat to a single or even more surfaces of the support metal, and then rolled or drawn to a recommended thickness. The karat gold should be no less than 1/10 from the entire weight.

Gold Plate shows that a layer of plating of 10-karat gold or much better have been bonded with a base metal. The karat gold content might be under 1/20, however it should be correctly determined by weight when it comes to total metal content.

Gold Leaf is just gold plating which has been pounded and appped manually.

Vermeil describes gold plating that is no less than 15 microns thick (one micron it is a milponth of an inch).
