List down some key points about jewel diamond from given text
1.	With its atoms grouped in what is known as a diamond cubic crystal structure, diamond is a solid form of the element carbon.
2.	The chemically stable form of carbon at room temperature and pressure is another solid form of carbon known as graphite, but diamond is metastable and only slightly converts to it under those conditions.
3.	Because of its superior hardness and thermal conductivity compared to other natural materials, diamond is frequently employed in high-tech industrial products like cutting and polishing equipment.
4.	They also allow materials to be subjected to pressures observed at great depths in the Earth in diamond anvil cells.
