About this 1.55ct lab-grown radiant diamond

This 1.55ct lab-grown radiant sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2516433719. Listed at 22 retailers as of November 4, 2026, with prices from £351 to £1,746, a £1,395 spread on the same certified stone. Brilliant Earth lists it at £1,746. 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.
