This 1.4ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG555298837 or 555298837. Listed at 9 retailers as of November 1, 2026, with prices from $279 to $1,658, a $1,380 spread on the same certified stone. Rare Carat lists it at $1,658. 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.
