About this 1.25ct lab-grown princess diamond

This 1.25ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG845669435 or 845669435. Listed at 12 retailers as of November 4, 2026, with prices from £146 to £833, a £686 spread on the same certified stone. Reve Diamonds lists it at £833. 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.
