This 1.05ct lab-grown princess sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG844684015 or 844684015. Listed at 12 retailers as of October 25, 2026, with prices from $278 to $1,138, a $860 spread on the same certified stone. MOH London lists it at $1,138. 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.
