This 1.98ct 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 very-good cut grade and certified by IGI LG818604361 or 818604361. Listed at 3 retailers as of November 3, 2026, with prices from $428 to $1,682, a $1,254 spread on the same certified stone. Brilliance lists it at $1,682. 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.
