Diamondi yabwino kwambiri ya diamondi ya akatswiri okhala ndi njira yosinthira kwambiri ndi zitsulo zitsulo. Pad ndi nkhanza kwambiri ndipo zisindikizo zimayenda mwachangu kwambiri kuposa momwe zimakhalira. Mosiyana ndi mapepala a rentin, mapepala a diamondi sasintha mtunduwo mwalawo, amasintha mwachangu, amawala, ndipo samakhala osalala pamizere ya konkriti. Zotsatira zopukutira zopukutira za pad yopukutira zimapangitsa acid over acid ndi alkalin corrossion, yomwe ndi yabwino kugwiritsa ntchito kukhitchini kunja ndi madera ena pomwe acid ndi alkali kuphukira.
