About this 2.57ct lab-grown cushion diamond

This 2.57ct 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 LG612329145 or 612329145. Listed at 5 retailers as of October 29, 2026, with prices from $636 to $2,136, a $1,500 spread on the same certified stone. MOH London lists it at $2,136. 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.
