About this 3.18ct lab-grown cushion diamond

This 3.18ct lab-grown cushion sits in the three to five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG476178000 or 476178000. Listed at 7 retailers as of November 5, 2026, with prices from $3,769 to $11,118, a $7,348 spread on the same certified stone. MOH London lists it at $11,118. 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.
