Diamonds are made of the same material whether they are old cut, single cut or rose cut, or Round brilliant cut. It is only different cuts as per its name “Old Cut” it was cut by hand and much different than RBC. Old cut diamonds are more rustic and organic look just because it is all hand made. Old cut facets are more rounded, and each facet has slight imperfection just because it was cut by a human hand and depending on the skill of each diamond cutter, that is why it is never the same each diamond has its unique shape and character.
