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 E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG519227854 or 519227854. Listed at 16 retailers as of October 29, 2026, with prices from $454 to $2,253, a $1,799 spread on the same certified stone. Brilliant Earth lists it at $2,253. 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.
