About this 1.05ct lab-grown cushion diamond

This 1.05ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG596345557 or 596345557. Listed at 9 retailers as of November 1, 2026, with prices from $265 to $1,382, a $1,117 spread on the same certified stone. MOH London lists it at $1,382. 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.
