About this 1.02ct lab-grown cushion diamond

This 1.02ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG510187152 or 510187152. Listed at 6 retailers as of October 26, 2026, with prices from $311 to $1,055, a $744 spread on the same certified stone. MOH London lists it at $1,055. 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.
