About this 3ct lab-grown cushion diamond

This 3ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG519243976 or 519243976. Listed at 6 retailers as of November 3, 2026, with prices from $1,179 to $4,012, a $2,833 spread on the same certified stone. MOH London lists it at $4,012. 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.
