buy a nitric acid test kit; They run about $20-$30 on E-bay. Rub the metal onto the stone firmly rub the metal onto the stone firmly, drip some nitric acid on the rubbing on the stone- if the rubbing stays strong, your piece is gold. If it turns orange your piece is likely a lower karat.
If the rubbing; Disappears or turns green- your piece is fake.
Gold is non-ferrous and therefore is not attracted by a magnet. There are other metal that are attracted by a magnet but gold is not one of them. You can tell what is a ferrous metal and what is a non ferrous one but you cannot identify gold.
To tell if gold is real or fake, measure its density. The density of gold, 19.3 grams / cm3, is much higher than most other metals. Even lead has a density of only 11.4 g/cm3 -- platinum, iridium, osmium, and neptunium are the only metals that have a density over 20 g/cm3! (For comparison the density of water is only 1 g/cm3).
the mineral that is called fools gold is phyrite because it looks just like gold. some people might think that phyrite is gold but it's not. phyrite is common than gold which would make it less valuable. if you want to tell whether the mineral is phyrite or gold found out how the streak of gold and phyrite is
larger pieces of pyrite will crumble when a knife is pressed into them. A rock which is "peppered" with many small pieces of gold will sound off with a metal detector, pyrite will not. Scratching a larger piece of pyrite will produce a sulfur smell. fool's gold is another word for pyrite.
to tell someone to do something for a reason
We tell real gold by its weight.
How can I tell gold
To test if something is real gold using a magnet, place the magnet near the item. If the item is attracted to the magnet, it is not real gold as gold is not magnetic. However, if the item is not attracted to the magnet, it may be real gold. It's important to note that this is not a definitive test and other methods, such as acid testing, are more accurate for determining gold authenticity.
no
by identify the color
Sounds like you have a 14 caret white gold necklace made in Italy. Yes, it is gold and is fine jewelry not costume or play. It is real. When you see 14K on something that means it is good and not junk.
by pooing on it
You can tell if you have a real gold necklace by checking its hardness, luster, specific gravity, streak, cleavage, and fracture, if all the properties match with the properties of gold you have a gold necklace.
One can tell if something is 24k gold by poking it with a sharp object. Gold is a soft metal, and the higher the karat the softer the metal, therefore if it makes a dent or leaves a mark, then the gold is 24k. Also, 24k gold is much more yellow, so, the color can help to identify 24k gold. And finally, bringing it to a jeweler to get it appraised will help to determine if it is 24k gold.
ask a gold smith
You can tell by looking at the claps . It should have it engraved.
In the world market any 24k soft yellow gold metal it is not real because don't has stable value and it's too soft and is not has " Life Time Guaranties " for jewelry creation , even the alloys yellow gold plated it's long time years " BIG SCAMS " !!!
