Have you ever heard of the Moh's scale? I believe quartz ranks 7 and diamond 10. If you can obtain topaz which is more common then Corundum and it leaves a streak on the mineral then the mineral is Quartz, but if the topaz or coundum is scratched then it is indeed a valuable diamond.
I would say that the easiest way is to use electronic diamond tester, which is basically a thermal conductivity tester. Thermal conductivity tester briefly heats diamond up and measures dissipation of heat in your sample. Different gemstones conduct heat differently.
Thermal conductivity tester does not require your sample to be polished or cut. The only condition is that you need to be able to touch actual diamond with the tip of the tester and not some foreign material or inclusion.

In order to use corundum to test the authenticity of the diamond, hold the corundum up against the suspected diamond and see the diamond to scratch a line on the corundum by rubbing the two gems together. If your gem does scratch corundum, it's definitely diamond.
You may be thinking of a Herkimer diamond, which is quartz, not diamond.
No. A diamond is a diamond: quartz is quartz. Both have different chemical elements and different molecular structures.
Quartz diamond crystal, commonly known as Herkirmer diamond, is not the same as diamond. A Herkimer diamond can be set in a wedding ring.
There are many differences between quartz and diamond. Primarily, quartz is much softer than diamond. Damond's hardness measurement of 10 -- on the Mohs scale -- is the highest hardness level. Quartz Locations: Brazil, Madagascar, Mozambique; Colors Found: Various; Family: Quartz Hardness: 7.00; Refractive Index: 1.50; Relative Density: 2.60 - 2.70 Diamond Locations: all continents except Europe and Antarctica; Colors Found: Various; Family: Carbon Hardness: 10.00; Refractive Index: 2.41; Relative Density: 3.50 Quartz and diamond have different chemical compositions: diamond is pure carbon, quartz is silicon dioxide.
The field test for raw diamond is 'extreme hardness'.
The field test for diamond is 'extreme hardness'. If you believe that you've found a diamond stone, you can take it to a jeweler, who will apply a probe and verify your find as a diamond stone, or not.

No. A diamond is a diamond: quartz is quartz. Both have different chemical elements and different molecular structures.
Quartz is silicon dioxide (sand). Diamond is an allotropic form of carbon.
Diamond is composed of the element carbon, and quartz is composed of the elements silicon and oxygen.
Diamond is a non-quartz gemstone.
Quartz diamond crystal, commonly known as Herkirmer diamond, is not the same as diamond. A Herkimer diamond can be set in a wedding ring.
No. Diamond is formed in carbon.
No.
No. Only a diamond can scratch another diamond.
There are double-terminated quartz crystals that have remarkable clarity and smooth crystal faces, which have non-scientifically been referred to as diamond quartz--the Herkimer Diamond is one so-named type of quartz crystal.
