About this 0.53ct natural radiant diamond

This 0.53ct natural radiant sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6492845217. Listed at 9 retailers as of November 6, 2026, with prices from $915 to $2,109, a $1,194 spread on the same certified stone. MOH London lists it at $2,109. 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.
