About this 1.5ct lab-grown round diamond

This 1.5ct lab-grown round sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG770640343 or 770640343. Listed at 24 retailers as of October 28, 2026, with prices from £192 to £1,127, a £935 spread on the same certified stone. Brilliant Earth lists it at £1,127. 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.
