About this 1.39ct lab-grown princess diamond

This 1.39ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG694554174 or 694554174. Listed at 6 retailers as of November 4, 2026, with prices from £299 to £794, a £495 spread on the same certified stone. MOH London lists it at £794. 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.
