About this 2.51ct natural radiant diamond

This 2.51ct natural radiant sits in the two to three carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7566494799. Listed at 10 retailers as of November 1, 2026, with prices from $20,789 to $37,089, a $16,299 spread on the same certified stone. MOH London lists it at $37,089. 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.
