The journey from “rough” stone to Rosendorff diamond is a long and arduous one and only the finest stones are deemed worthy of being considered a Rosendorff diamond. As Craig Rosendorff himself says....”Few stones are fine enough to travel the road to perfection.”

Diamonds evolve over millions of years deep within the earth’s core. Nature is the consummate magician, creating these incomparable gems and bestowing them upon us “rarely”, lest we take them for granted. Over 250 tonnes of diamond ore will be excavated to produce just one carat of beautiful gem quality diamond.

Once mined the diamond crystals are separated from the ore and
the diamond “rough” is prepared for the cutting process. The rarity
of the diamond is further reiterated when you consider that up to
85% of the diamond roughs are then also rejected as not being up
to gem quality standard.
