About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-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 1112367429. Listed at 17 retailers as of November 4, 2026, with prices from $2,161 to $4,614, a $2,453 spread on the same certified stone. MOH London lists it at $4,614. 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.
