About this 1.68ct lab-grown cushion diamond

This 1.68ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG538290299 or 538290299. Listed at 11 retailers as of November 1, 2026, with prices from $469 to $2,212, a $1,742 spread on the same certified stone. Brilliant Earth lists it at $2,212. 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.
