About this 1.88ct lab-grown cushion diamond

This 1.88ct 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 LG747570783 or 747570783. Listed at 11 retailers as of November 1, 2026, with prices from $417 to $2,510, a $2,093 spread on the same certified stone. Brilliant Earth lists it at $2,510. 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.
