Your answer depends on what property interests you: clarity or carat weight, or whether or not your 'big natural...stone' is a diamond.
A local jeweler can help you understand the stone that you take in to be tested.
One answer could be the inexperience of the diamond viewer. Another is that many diamonds are no bigger than a grain of rice, also their color can be missed against the natural color of the ground. The field test for diamond is 'extreme hardness'. As well only about 25% of natural diamonds are of gem-stone quality, so the other 75% of diamonds found will not appear to possess a natural clarity or colour commonly associated with gem-stone quality rocks.

Yes. white alloys, but has to pass acid test and magnet test;and its not still.
The best you can do is to get a diamond grading report from the Gemological Institute of America. The reports tell you everything about the diamond, from the color, cut, clarity and how big the diamond is. The report will immediately know if the gem is fake or not.The value of a diamond depends on its cut, its clarity, its colour and its carat weight. A local jeweler can give you the answer you want.
I've been told true diamonds will cut glass & if you have it examined by a Jeweler DO NOT leave it overnight as you may receive a fake back. GOOD LUCK. Heavy Liquid Method: Keeping the diamond in "clerici diluted solution" (poisonous) of S.G. 3.52 will suspend (neither floats nor sinks) whereas other stones will either float or sink. The actual cleric solution has S.G. of 4.00 but with added "methylene iodide" and with help of indicator stone (diamond) will make the solution of similar S.G. that of a diamond i.e. 3.52. This "clerici diluted solution" is one heck a solution to identify diamond from rest of the gemstone world.
The field test for a diamond stone is its extremehardness. Lacking any tool to test extreme hardness, take the raw stone to a jeweler, who can use a probe to confirm that the stone is or is not a diamond.
DON'T heat test a diamoind. Leave it to a jeweller. If you apply heat to a diamond it will become soot (graphite).

Yes, when testing for a diamond, the test determines whether or not the stone conducts heat -- regardless of the colour of the stone.
Using a diamond probe, a jeweler can help you determine whether or not the stone you have is a diamond.
The differences between natural diamonds and lab-created diamonds are best determined by a trained and certified gemologist. even if it is damaged and has a rough edge. If the diamond is a raw diamond and your query is whether or not the stone is a diamond or not, the field test for diamond is hardness. A diamond rock will scratch everything.
A transparent stone can be made of any material. If you suspect that it is a diamond, the field test for diamond is extreme hardness.
A gold journal would be the best metal, since it does not oxidize (rust). A stone journal made of diamond would be the strongest, since it is the hardest natural stone.
You take it to a jeweler who can test the stone and verify that it is a diamond, or that it is imitation.

The field test for a diamond is hardness. You can scratch another rock or a test piece of glass with the edge of the stone. Note, however, that the field test is not conclusive.
The field test for diamond is extreme hardness. If you are not equipped to perform this test, a local jeweler can attach a probe to your stone, to determine whether or not it is a diamond.
