About this 3.11ct lab-grown cushion diamond

This 3.11ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG440017333 or 440017333. Listed at 7 retailers as of November 1, 2026, with prices from $3,658 to $8,631, a $4,973 spread on the same certified stone. MOH London lists it at $8,631. 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.
