This 1.71ct lab-grown princess sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG440014055 or 440014055. Listed at 10 retailers as of October 30, 2026, with prices from €1,318 to €4,369, a €3,050 spread on the same certified stone. MOH London lists it at €4,369. 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.
