This 1.72ct lab-grown princess sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG579399677 or 579399677. Listed at 19 retailers as of October 30, 2026, with prices from $429 to $3,655, a $3,226 spread on the same certified stone. Do Amore Diamonds lists it at $3,655. 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.
