About this 1.5ct lab-grown radiant diamond

This 1.5ct lab-grown radiant sits in the one-and-a-half to two carat band, graded E 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 7381890906. Listed at 9 retailers as of October 29, 2026, with prices from £261 to £1,254, a £993 spread on the same certified stone. MOH London lists it at £1,254. 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.
