About this 1.59ct lab-grown princess diamond

This 1.59ct lab-grown princess sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG818641577 or 818641577. Listed at 9 retailers as of November 1, 2026, with prices from £305 to £993, a £688 spread on the same certified stone. Rare Carat lists it at £993. 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.
