About this 1.17ct lab-grown cushion diamond

This 1.17ct lab-grown cushion sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG617403479 or 617403479. Listed at 6 retailers as of October 26, 2026, with prices from $270 to $932, a $662 spread on the same certified stone. MOH London lists it at $932. 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.
