This 1.51ct lab-grown radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG761552504 or 761552504. Listed at 25 retailers as of October 28, 2026, with prices from £225 to £1,060, a £835 spread on the same certified stone. Reve Diamonds lists it at £1,060. 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.
