This 1.51ct lab-grown princess sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG447000695 or 447000695. Listed at 10 retailers as of October 30, 2026, with prices from $1,854 to $6,142, a $4,288 spread on the same certified stone. MOH London lists it at $6,142. 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.
