About this 1.09ct lab-grown cushion diamond

This 1.09ct lab-grown cushion sits in the classic one-carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG593372531 or 593372531. Listed at 5 retailers as of November 5, 2026, with prices from $435 to $1,890, a $1,456 spread on the same certified stone. MOH London lists it at $1,890. 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.
