This 1.28ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG551276144 or 551276144. Listed at 2 retailers as of November 1, 2026, with prices from $437 to $1,119, a $682 spread on the same certified stone. MOH London lists it at $1,119. 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.
