About this 2.51ct lab-grown cushion diamond

This 2.51ct lab-grown cushion sits in the two to three carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2486286724. Listed at 14 retailers as of October 25, 2026, with prices from $736 to $3,218, a $2,482 spread on the same certified stone. MOH London lists it at $3,218. 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.
