Round Brilliant Cut
Dops for Round Diamonds
A round brilliant diamond depends on perfect symmetry — every facet has to meet the wheel at exactly the same angle around the full 360°. Our round diamond dops are centred and sized to hold the stone dead-true, so blocking, faceting and final polish stay consistent from the first facet to the last.
- Precision-centred hold for true round symmetry
- Sized to the stone for a firm, stable grip through every stage
- Available as standard dops or our katora-style bowl dops
- Built for repeatable results across production batches
Why Precision Matters
Symmetry starts with the dop
If a round diamond sits even slightly off-centre in its dop, the resulting facets won’t align — costing brilliance and yield. Our round dops and katora dops are made to keep the stone’s axis true, so polishers can focus on the cut, not the hold.
True Centring
Each dop is fitted to keep the diamond’s culet and table aligned on axis.
Katora Style Option
Our bowl-style katora dops suit high-volume round diamond polishing lines.
