This is often aided by isotopic relationship and modeling of your geological background. Then surveyors will have to Visit the location and gather samples, on the lookout for kimberlite fragments or indicator minerals. The latter have compositions that mirror the problems wherever diamonds form, like Excessive soften depletion or significant pressures in eclogites. Even so, indicator minerals might be deceptive; a better technique is geothermobarometry, where by the compositions of minerals are analyzed as if they were in equilibrium with mantle minerals.[76]
Initiatives are increasingly being produced to advertise additional sustainable and ethical methods in diamond Diamond mining and distribution, by using a target transparency and good trade.
Observation and speculation...

Small faucets lead to breaking, enabling the pressure to release. Even though it is fairly uncommon for diamonds to break in this way, It's really a truth of the matter to concentrate on.
Cut: The standard of design and style and craftsmanship used in slicing a diamond is exactly what determines its visual appearance. The angles to which the aspects are cut, the proportions of the design, and the standard of the sharpening are what determine its deal with-up physical appearance, brilliance, scintillation, sample, and hearth.
