About this 1.13ct lab-grown cushion diamond

This 1.13ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG830620256 or 830620256. Listed at 8 retailers as of October 30, 2026, with prices from £152 to £551, a £400 spread on the same certified stone. Michael Trio lists it at £551. 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.
