About this 1.42ct lab-grown cushion diamond

This 1.42ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG605314531 or 605314531. Listed at 4 retailers as of November 6, 2026, with prices from $1,145 to $1,575, a $430 spread on the same certified stone. Zales lists it at $1,575. 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.
