I dont know i was trying to figure out the same thing because im color blind and im scrapping metal from old circuts on free time to make money.
Well, the difference between gold and gold overlay, is that the gold 24k it is pure yellow gold metal; and yellow gold alloys it is 22k thru 10k Rhodium Plated. But is not white gold plated. Because it is yellow gold alloy's include copper, and Rhodium plated. That it is gold overlay.
Brass is an alloy of copper and zinc, giving it a more yellow appearance with slight red tones. Gold, on the other hand, is a precious metal with a distinct bright yellow color and is much softer compared to brass. One way to differentiate them is through a magnet, as brass is not magnetic but gold is not magnetic.
One way to tell the difference between 9ct gold and gold-plated jewelry is to look for hallmark stamps on the piece. 9ct gold will have a specific hallmark indicating its purity level, while gold-plated jewelry may not have any such stamp. Additionally, you can also do a simple acid test or consult with a jeweler to determine the material's composition.
Nickel silver is an alloy of nickel, copper, and zinc, while sterling silver is an alloy of silver and copper. You can tell the difference between the two by looking for a marking such as "925," which indicates sterling silver's higher silver content compared to nickel silver. Sterling silver will also have a brighter appearance and may tarnish less than nickel silver.
Prospectors used the physical property of density to differentiate between iron pyrite and gold. Gold is denser than iron pyrite, so prospectors could use the weight of a sample to determine whether it was more likely to be gold or iron pyrite.
They would smash it with a rock.
well uh..... ask my science teacher

Aucuga is an alloy gold-copper-gallium.
The brass has much lighter color (yellowish to light reddish), then the copper (reddish brown). The brass is copper mixed with zinc. The more copper in the mix, the darker the color.
Iron Oxide. Pyrite is known also as "Fool's Gold"
You can differentiate between a bar of iron and a bar of copper by testing their magnetic properties - iron is attracted to magnets, while copper is not. A bar magnet will attract small iron objects, while a bar of copper will not be attracted.

how can you tell the difference between a tortoise and a turtle by shell in picture
Can you tell the difference between Vyvanse and Concerta in a drug test
