About this 1.51ct lab-grown cushion diamond

This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG560215971 or 560215971. Listed at 12 retailers as of November 6, 2026, with prices from $269 to $1,387, a $1,118 spread on the same certified stone. MOH London lists it at $1,387. 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.
