This 1.55ct 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 LG607307879 or 607307879. Listed at 14 retailers as of November 6, 2026, with prices from $425 to $3,362, a $2,937 spread on the same certified stone. Do Amore Diamonds lists it at $3,362. 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.
