This 1.01ct lab-grown princess sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840664734 or 840664734. Listed at 21 retailers as of October 25, 2026, with prices from £123 to £809, a £686 spread on the same certified stone. Reve Diamonds lists it at £809. 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.
