About this 0.59ct natural radiant diamond

This 0.59ct natural radiant sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1538587701. Listed at 5 retailers as of October 31, 2026, with prices from £475 to £814, a £339 spread on the same certified stone. GemTrove lists it at £814. 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.
