This 5.09ct lab-grown princess sits in the over five carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG625498207 or 625498207. Listed at 11 retailers as of October 29, 2026, with prices from $1,055 to $4,236, a $3,181 spread on the same certified stone. MOH London lists it at $4,236. 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.
