Take a cup or glass, fill it up with water, now bring the gold that you want to test. Drop it into this filled glass. If the gold floats, it is surely not real but if the gold sinks to the end of the glass then it is pure gold. The real gold will sink due to being a heavy metal.
The color of pure Gold is bright golden yellow, but the greater the silver content, the whiter its color is. Much of the gold mined is actually from gold ore rather then actual Gold specimens. The ore is often brown, iron-stained rock or massive white Quartz, and usually contains only minute traces of gold.
True Gold's Color
Raw gold appears brassy yellow and bright. If you think it is gold, place your hand between it and the sun to create shade over the gold. If it still appears bright in the pan, chances are that it is real gold. Fool's gold does not appear as bright when shaded.
Hold your gold nugget to the light and see if it sparkles. While real gold has a shiny, metallic surface that glistens, it does not create a glittery effect. On the other hand, fool's gold twinkles as it reflects the light.
To test a rock for gold, first perform nondestructive visual inspections and tests for weight and magnetism. You can also use destructive methods such as testing hardness, streak, ductility, or pulverizing and panning the powder.
Pure gold on its own cannot stick to a magnet. However, if you have an alloy of gold, then it could stick to a magnet. An example of a gold alloy that may stick to a magnet is gold with over 20% of its atoms replaced by iron.
The value of your raw gold depends on the same factors as other types of gold: How much gold you have, and how pure it is. Most raw gold is about 18K and is often combined with other metals like silver, copper, and lead.
One thing is for sure: the raw material gold is rare in the world, although it can be found almost everywhere in the earth's crust. But unfortunately, in many cases the amount of the raw material gold is too small, so that mining is only really worthwhile in certain areas.
Magnet Test
Gold is a non-reactive and non-magnetic metal, whereas most other metals have magnetic properties. Therefore, if you put real gold near a magnet you will notice no change in it. However, if there are other metals present in the piece of gold, it will be attracted to the magnet.
You want to look for signs of gold like black sands, pyrite and small quartz, as these are all usually good indicators of gold being in the area. Garnets may also be present, often appearing in many shades of colors including red, orange and pink!
It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in pure form.
24 carat is pure gold with no other metals. Lower caratages contain less gold; 18 carat gold contains 75 per cent gold and 25 per cent other metals, often copper or silver.
Fool's gold may boast immense resemblance to gold but doesn't have the properties of gold. It's shiny, beautiful, and even glitters when exposed to direct light. But unlike real gold, it's not shiny when not in direct light.
So if you find a few flakes or nuggets on your property, your best course of action is simply to put it away somewhere as a collectible or for a rainy day. If you find a large amount of gold, you may be in for some legal headaches, but with the right advice, you can still come away with a profit from your find.
In Australia, the current price of gold is 2,874.05 Australian dollar per ounce. The price of gold per gram is 92.4 Australian dollar.

Oxidation. Special acids when applied to the surface of gold cause it to darken or “oxidize.” Blackening. In blackening, a paint-like liquid is brushed onto the surface and worked down into the nooks and crannies.
Although most gold bars are made of high purity, usually bearing 99.9 per cent fineness, raw gold isn't as pure. Since it comes straight from the earth, it is alloyed with different metals that are usually refined to produce pure gold.
Q: HOW LONG CAN YOU LEAVE GOLD IN VINEGAR? A: When you clean jewelry with vinegar, you can submerge your gold jewelry in the vinegar solution for up to 20 minutes, but it's best not to go beyond that point.
