This 1ct lab-grown princess sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG846656678 or 846656678. Listed at 14 retailers as of October 24, 2026, with prices from $221 to $1,278, a $1,057 spread on the same certified stone. Brilliant Earth lists it at $1,278. 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.
