This 2.31ct lab-grown princess sits in the two to three carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG506193721 or 506193721. Listed at 11 retailers as of October 30, 2026, with prices from $1,213 to $4,522, a $3,309 spread on the same certified stone. MOH London lists it at $4,522. 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.
