Quartz diamond crystal, commonly known as Herkirmer diamond, is not the same as diamond.
A Herkimer diamond can be set in a wedding ring.
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 is a type of crystal. There are many different types of crystals. A crystal is any solid with a regular repeating atomic/molecular structure. Quartz is a crystal that is composed of silicon dioxide. Diamond is a crystal of carbon. Rubies and sapphires are crystals of aluminum oxide. Salt is a crystal of sodium chloride. Even organic compounds, like sugar, can form crystals. Semi-crystalline material is also known, and an example of that is the common plastic HDPE (high density polyethylene).
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.
A quartz temperature sensor inside a vial in a freeze dryer works by measuring the frequency of the quartz crystal. The quartz crystal is designed to vibrate at a specific frequency when it is exposed to a certain temperature. As the temperature inside the vial changes, the frequency of the quartz crystal changes as well. The frequency is then measured by the temperature sensor and compared to a reference temperature, allowing the freeze dryer to accurately measure and control the temperature of the vial.
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.
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.
Gem Diamond (1967) Mineral Quartz Crystal (1967) Rock Bauxite (1967)
It's state gem is the diamond and its state mineral is the quartz crystal.
The diamond is the hardest mineral and is the state mineral of Arkansas.
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.
There are substitute faux-gem stones that jewelers use to display and show off their settings. Some are man-made; others are semi-precious stones, such as quartz or crystal, even white sapphire. These substitutions are for 'looks' only. There is no substitute material for diamond when it comes to hardness.
Amethyst is a variety of crystal quartz.
Pure quartz is a homomogeneous crystal.
Quartz.
It depends on the mineral composition of the crystal. White quartz crystal is called "Milk Quartz" or "Milky Quartz".
