About this 2.05ct natural radiant diamond

This 2.05ct natural radiant sits in the two to three carat band, graded G 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 5131387720. Listed at 4 retailers as of November 4, 2026, with prices from $28,719 to $43,862, a $15,142 spread on the same certified stone. MOH London lists it at $43,862. 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.
