About this 5.03ct natural radiant diamond

This 5.03ct natural radiant sits in the over five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1568398267. Listed at 4 retailers as of November 1, 2026, with prices from $183,254 to $299,264, a $116,011 spread on the same certified stone. MOH London lists it at $299,264. 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.
