Use a magnet to see if it responds. If it is attracted to the magnet solidly, it is NOT gold, if it has a light magnetic attraction, it may be plated or impure. Pure gold does not respond to a magnet.
If the item passes the magnet test, you will need to buy a nitric acid test kit on eBay. Acid testing kits run about $20 - $30 and are very simple to use. Rub your item firmly on the testing stone that comes with the kit, drip a single drop of acid onto the area you have just polished. If the area stays the same color, your item is gold. If it turns a yellow-orange color it may be gold but a lower quality karat. If the area changes any other color - it is not gold.
Check for any mark in the jewelry, usually gold jewelry has standard hallmarks like 916, 750, 18kt, 14kt, 10kt, etc. (Costume jewelry might not contain such symbols.)
If the object is (apparently) solid gold, with no stones or other materials attached, one can weigh it suspended by a thin thread in air and then weigh it again submersed in water, using a sensitive laboratory scale. From the difference in weights one can calculate its density. Since pure gold has a known density, if the number one gets is different, it's likely an alloy or may be a base metal with a gold plating. A method similar to this was employed by the Greek polymath and inventor Archimedes (c. 287 BC - c. 212 BC), when he was asked to prove whether the king's crown was of pure gold without damaging or destroying the crown.
Since gold is an unusually soft metal, you might see how soft it is (although such tests can damage the object in question - historically, people used to actually bite gold coins to see how easily they can be deformed, but then there would be tooth marks in the coins). The more precise method (which requires some equipment) is to measure the volume of the object, using a graduated cylinder (see how far the water level rises when the object is dropped in) and then weigh it, and calculate its precise density; gold is denser than any other metal with which it might be alloyed (osmium is denser, but no one adds osmium to gold, since it is even more expensive).
White gold has a certain sound when dropped...the sound is usually high pitched. Now if its not real.....then when dropped it will make a very low pitched sound.
If it bends, it's real. If it doesn't, it's fake.
You bite it. You can dent it with your teeth
bite them and see but not to hard.
We tell real gold by its weight.
You can tell if a ring is real gold or not by putting it near a magnet. If the ring is attracted to the magnet it is not real gold, real gold is not magnetic at all.
White gold is an alloy of gold and a white metal, usually nickel or palladium. It is as real as any other form of gold.
no
yes, but white gold with Rhodium plated is not real white gold !
It won't unless it's not real white gold. White gold is platinum, it's very stable.
Yes
Well, 22k white gold price in India it is the same price that Yellow gold metal. Because it is not Real white gold. Well, only " Pure Solid White gold Formula " it is Real white gold... Yellow gold metal, copper, with Rhodium Plated is not white gold, sale in India!Sincerely: Professional Jewelry!
