This 1.75ct lab-grown princess sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG582390700 or 582390700. Listed at 18 retailers as of October 30, 2026, with prices from $687 to $6,086, a $5,399 spread on the same certified stone. Do Amore Diamonds lists it at $6,086. 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.
