About this 1.36ct lab-grown cushion diamond

This 1.36ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG708585401 or 708585401. Listed at 10 retailers as of October 29, 2026, with prices from $217 to $1,126, a $909 spread on the same certified stone. MOH London lists it at $1,126. 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.
