This 1.7ct lab-grown princess sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG528207701 or 528207701. Listed at 19 retailers as of October 27, 2026, with prices from $351 to $2,071, a $1,720 spread on the same certified stone. Brilliant Earth lists it at $2,071. 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.
