Merging: If you want to merge an old ring that is possibly a heirloom, with a new one, then remounting may prove helpful.
A diamond cut is graded according to the measurements of the pavilion and crown angles. It takes a trained eye to judge its quality. Cut grades need to follow the dictates of standardized table ratio and length of lower girdle facets. Diamond cutting is an art that transforms the rough stone into a faceted spectacle. The cutting process involves extensive cleaving and polishing, beyond planning and consistent monitoring.
The strength of the magnetic field and the intense pressure induce the necessary thermal energy required for the process. Some researchers have also achieved similar results by utilizing a focused high-intensity laser beam and high pressure conditions. Later, when the pressure is reduced, the molten diamond re-solidifies into a solid crystal. This behavior has prompted scientists to ponder over the possible existence of seas of liquid nitrogen on planets like Neptune and Uranus, as a consequence of intense pressure and abundance of carbon.
