About this 1.81ct lab-grown princess diamond

This 1.81ct 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 standard cut grade and certified by IGI LG611368058 or 611368058. Listed at 18 retailers as of October 29, 2026, with prices from £178 to £1,097, a £919 spread on the same certified stone. Brilliant Earth lists it at £1,097. 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.
