About this 1.62ct lab-grown cushion diamond

This 1.62ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG588350311 or 588350311. Listed at 7 retailers as of November 1, 2026, with prices from $522 to $1,675, a $1,154 spread on the same certified stone. Brilliant Earth lists it at $1,675. 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.
