This 1.51ct lab-grown princess sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG644479922 or 644479922. Listed at 7 retailers as of November 1, 2026, with prices from $542 to $1,555, a $1,013 spread on the same certified stone. MOH London lists it at $1,555. 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.
