About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557200122. Listed at 3 retailers as of November 3, 2026, with prices from £9,049 to £10,688, a £1,640 spread on the same certified stone. Blue Nile lists it at £10,688. 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.
