About this 1.51ct lab-grown cushion diamond

This 1.51ct lab-grown cushion sits in the one-and-a-half to two 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 2497331214. Listed at 16 retailers as of November 6, 2026, with prices from $529 to $2,285, a $1,756 spread on the same certified stone. MOH London lists it at $2,285. 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.
