About this 3.03ct natural radiant diamond

This 3.03ct natural radiant sits in the three to five 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 2557414608. Listed at 17 retailers as of October 31, 2026, with prices from $36,340 to $63,214, a $26,874 spread on the same certified stone. MOH London lists it at $63,214. 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.
