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 F 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 1438804643. Listed at 19 retailers as of November 6, 2026, with prices from £240 to £2,129, a £1,889 spread on the same certified stone. Do Amore Diamonds lists it at £2,129. 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.
