About this 1.28ct lab-grown princess diamond

This 1.28ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG729572205 or 729572205. Listed at 25 retailers as of October 27, 2026, with prices from $330 to $2,354, a $2,024 spread on the same certified stone. Queensmith lists it at $2,354. 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.
