This 1.23ct lab-grown princess sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG706531171 or 706531171. Listed at 7 retailers as of November 5, 2026, with prices from $709 to $1,865, a $1,156 spread on the same certified stone. MOH London lists it at $1,865. 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.
