About this 1.55ct lab-grown cushion diamond

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 1, 2026, with prices from $292 to $2,310, a $2,018 spread on the same certified stone. Do Amore Diamonds lists it at $2,310. 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.
