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 LG593381373 or 593381373. Listed at 19 retailers as of October 30, 2026, with prices from $509 to $2,438, a $1,929 spread on the same certified stone. Reve Diamonds lists it at $2,438. 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.
