The honor of aureate is measured in carats or karats, an ancient unit of measurement of weight. Pure gold is 24 carats, and 50 percentage aureate is 12 carats. To get the share purity of gold, just divide the carat value by 24 and multiply by 100. In the United States, selling gold below 10 carats as gold jewelry is prohibited.

A diverseness of amber colors and alloys are available. White gold looks like ash grey, but it does n’t tarnish. It ‘s much coated in rhodium to give it an particularly glistening look. Gold combined with enough copper can look pink or red. Since copper is relatively hard, it ‘s one of the most durable types of amber jewelry. This is the most durable type of gold since copper is a hard metallic. Green amber or electrum frequently contains silver, cadmium, and zinc. however, the purity of gold is responsible for most of its value, not its color .
Gold is n’t charismatic, so it should n’t respond to even the strongest rare earth magnets. however, the clasp on your jewelry could however be magnetic. There are besides many nonmagnetic metals that could look like gold .
How to Examine Gold Carefully
Use a overstate glass to look for any signs of discoloration. This could indicate jewelry that ‘s only goldplate. You should besides look for a honor authentication. This can be in carats or millesimal fineness. For exercise, pure gold will have a small engraving that says 24K or 999. It ‘s normally on the backs of earrings and the inside surfaces of rings. Necklaces and bracelets often have jewelry hallmarks on or near the clasp. The manufacturer ‘s stamp is nearby .
You should be mindful of hallmarks that indicate that jewelry is n’t amber. HGP means heavy or intemperate gold plate, and GP means goldplate. GF is gold-filled, and H.G.E. stands for hydrostatic gold electroplate. G.E.P. means gold electroplate. Common argent hallmarks include 800, 925 and 950 .
gold coins and bars normally have engravings with the purity of the gold, the slant, and mint marks. If you do n’t see a hallmark, it may have worn away over time. The jewelry could have besides been made before hallmarks became common in the 1950s. even if you see a hallmark that indicates pure aureate, the jewelry could be a bogus. Consider the expect of the authentication along with other factors before you decide whether jewelry is real gold .
Conduct a Scratch Test and a Skin Test

For this trial, you ‘ll need a black jeweler ‘s rock that ‘s particularly made for gold test, an unglazed porcelain tile, or an unglazed ceramic plate. You can buy a ceramic plate or a porcelain tile from a local hardware shop .
Scratching your gold could damage it, so you should conduct this test carefully. Rub the gold against the stone, tile, or plate securely adequate to leave a grade but not hard adequate to leave a detectable rub on the gold. If the gold is real, the tag or streak it produces should be aureate or yellow color. A black streak means you have pyrite or another imprint of fake gold. You can besides tell if amber jewelry is forge precisely by wearing it. many types of talk through one’s hat gold will stain or discolor your skin after about 15 minutes of contact .
Use a Chemical Gold Testing Kit
Chemical testing kits contain acids that could harm or damage fudge materials but not gold. You should only use this type of test on items that you do n’t mind damaging. flush if a pretty ring or bracelet does n’t contain gold, it could be valuable for its beauty and expressive style .
Be prepared to store the acids in the kit or dispose of them safely after use. Gold testing kits contain hydrochloric or azotic acerb and a dropper.

Nitric acidic will dissolve any metallic element that ‘s not gold. Putting a minor sum of azotic acidic on your jewelry will let you know if it ‘s pure gold. Fake gold or an alloy will cause a reaction. Before testing, use a abrupt phonograph needle to make a bantam scratch or indentation in the gold. Use the back of the jewelry if potential, and apply the acid and rinse it off arsenic soon as potential .
Some testing kits include unlike mixtures of azotic acerb and other components. The acids are labeled with karat levels, and a reaction with your aureate indicates that it matches the carat degree or is less saturated. No reaction is a sign of higher purity. many testing kits include gold test needles so you can compare the persuasiveness of the chemical reaction with gold samples that have verified carat levels. If you need to use more than one type of acid, rinse and dry your jewelry between applications.
