About this 3.15ct lab-grown cushion diamond

This 3.15ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG520290627 or 520290627. Listed at 8 retailers as of October 30, 2026, with prices from $1,664 to $6,841, a $5,177 spread on the same certified stone. MOH London lists it at $6,841. 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.
