About this 1.5ct lab-grown princess diamond

This 1.5ct lab-grown princess sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG700581232 or 700581232. Listed at 23 retailers as of November 4, 2026, with prices from $436 to $3,380, a $2,944 spread on the same certified stone. Brilliant Earth lists it at $3,380. 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.
