About this 2.03ct natural radiant diamond

This 2.03ct natural radiant sits in the two to three carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5513861017. Listed at 31 retailers as of November 4, 2026, with prices from $20,735 to $36,934, a $16,199 spread on the same certified stone. MOH London lists it at $36,934. 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.
