This 1.28ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG841654805 or 841654805. Listed at 22 retailers as of October 27, 2026, with prices from $290 to $1,715, a $1,425 spread on the same certified stone. Reve Diamonds lists it at $1,715. 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.
