About this 0.51ct lab-grown cushion diamond

This 0.51ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436073164 or 436073164. Listed at 6 retailers as of November 1, 2026, with prices from $422 to $2,207, a $1,785 spread on the same certified stone. MOH London lists it at $2,207. 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.
