About this 1.5ct lab-grown princess diamond

This 1.5ct lab-grown princess sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG615387281 or 615387281. Listed at 6 retailers as of November 3, 2026, with prices from £279 to £802, a £523 spread on the same certified stone. MOH London lists it at £802. 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.
