About this 0.51ct lab-grown cushion diamond

This 0.51ct lab-grown cushion sits in the half to three-quarter carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG620494548 or 620494548. Listed at 6 retailers as of November 1, 2026, with prices from €251 to €1,238, a €987 spread on the same certified stone. MOH London lists it at €1,238. 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.
