About this 2.06ct natural radiant diamond

This 2.06ct natural radiant sits in the two to three carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6401259379. Listed at 16 retailers as of November 1, 2026, with prices from £11,599 to £20,005, a £8,406 spread on the same certified stone. MOH London lists it at £20,005. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
