About this 1.06ct lab-grown cushion diamond

This 1.06ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG500148308 or 500148308. Listed at 7 retailers as of November 1, 2026, with prices from $456 to $2,117, a $1,660 spread on the same certified stone. MOH London lists it at $2,117. 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.
