Златна чистота
As the most malleable of all precious metals, gold is an excellent choice when crafting designs with very intricate details. Плюс, it’s resistant to rust, tarnish and corrosion. Pure gold is too soft for everyday wear, so it’s alloyed with a mixture of silver, copper and a trace of zinc, to give it strength and durability. This hardens the final product enough to last for many generations.
Karatage, denoted by a number followed by “k”, indicates purity, or how much of the metal in a piece of jewelry is gold. Karatage is expressed in 24ths, making 24k gold the highest karat gold. It has a rich and luxurious gold-yellow color, but unlike 14k or 18k gold, it’s far too malleable for everyday wear. If you’re unsure what karat your jewelry is, you can find out by looking for a number followed by a lower case “k” stamped somewhere on the piece.
Отличителни белези
Gold is commonly stamped with what’s known as a hallmark. The hallmark indicates the amount of pure gold content, and sometimes denotes the date of completion and country of origin. And under federal law, gold jewelry must be accompanied by a maker’s mark or registered trademark.
Blue Nile Gold
We carry jewelry that’s crafted in both 18k and 14k gold. Our 18k gold is an alloy of 75% gold with other metals to make it strong enough for everyday wear, and our 14k gold is an alloy of 58.3% gold and other metals. The minimum karat that is allowed to be sold as gold jewelry in the U.S. is 10k—an alloy of 41.7% Чисто злато. If you’re one of our European customers, you may be accustomed to a different gold karat scale. 585 is equivalent to our 14k gold, while 750 is the same as our 18k gold.
