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 I colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG436047377 or 436047377. Listed at 9 retailers as of October 26, 2026, with prices from $377 to $1,675, a $1,298 spread on the same certified stone. MOH London lists it at $1,675. 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.
