This 1.45ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG790661086 or 790661086. Listed at 3 retailers as of October 28, 2026, with prices from £1,114 to £1,637, a £523 spread on the same certified stone. Brilliant Earth lists it at £1,637. 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.
