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.
No! Diamonds are a pure form of carbon, while quartz is a silica-oxygen compound. According to Wikipedia quartz is the second most abundant mineral in the Earth's continental crust. It is a major component of sand.
Ionic bonds in compounds such as NaCl and covalent bonds in say diamond (C) and quartz (SiO2)
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.
Quartz
There are several differences, the primary one being that on the Mohs hardness scale, diamond is 10, quartz is 8. Quartz crystal is very hard, but diamond is harder.
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.
