About this 2.51ct lab-grown cushion diamond

This 2.51ct lab-grown cushion sits in the two to three carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG450015331 or 450015331. Listed at 7 retailers as of November 1, 2026, with prices from $849 to $2,856, a $2,007 spread on the same certified stone. MOH London lists it at $2,856. 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.
