This 1.73ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG784646408 or 784646408. Listed at 10 retailers as of November 1, 2026, with prices from $1,071 to $6,456, a $5,385 spread on the same certified stone. Do Amore Diamonds lists it at $6,456. 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.
