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 12 retailers as of October 31, 2026, with prices from $329 to $1,550, a $1,221 spread on the same certified stone. Brilliant Earth lists it at $1,550. 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.
