About this 1.4ct lab-grown cushion diamond

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 very-good cut grade and certified by IGI LG605370320 or 605370320. Listed at 17 retailers as of November 4, 2026, with prices from $360 to $2,435, a $2,075 spread on the same certified stone. Brilliant Earth lists it at $2,435. 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.
