About this 2.5ct lab-grown cushion diamond

This 2.5ct lab-grown cushion sits in the two to three carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG450012436 or 450012436. Listed at 13 retailers as of November 5, 2026, with prices from $826 to $4,673, a $3,848 spread on the same certified stone. MOH London lists it at $4,673. 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.
