Quartz is also used in the fashion jewellery-making industries. On comparing, you get the perfect shape of diamond and quartz. Both are not the same.

Key Takeaways

  1. Quartz is a mineral composed of silicon and oxygen, while diamond is a mineral composed of carbon atoms arranged in a crystalline structure.
  2. Quartz has a lower hardness rating on the Mohs scale than diamond, making it less resistant to scratches and abrasions, while diamond is one of the hardest substances on earth and is highly resistant to wear and tear.
  3. Quartz is much more abundant and affordable than diamond, which is rare and expensive due to its high demand and limited supply.

Quartz vs Diamond

Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon-oxygen tetrahedra. It is one of the most abundant minerals on Earth. Diamond is a mineral composed of carbon atoms arranged in a crystalline lattice structure. It is the hardest known natural material and has a high refractive index.

Quartz vs Diamond

Quartz is the most founded element on Earth.

It is crystalline and cut from the rock. The primary element is silicon, and oxygen combine and forms the quartz called silicon dioxide. It has some impurities in minor ranges like sodium, lithium, and potassium.

In early times the connection or attraction in quartz is larger than now. It was first originated or founded in 1530 in Greece.
