This 1.71ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG833692787 or 833692787. Listed at 16 retailers as of October 29, 2026, with prices from $399 to $2,506, a $2,107 spread on the same certified stone. Brilliant Earth lists it at $2,506. 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.
