About this 0.71ct lab-grown cushion diamond

This 0.71ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG698509317 or 698509317. Listed at 17 retailers as of October 26, 2026, with prices from £97 to £905, a £808 spread on the same certified stone. MOH London lists it at £905. 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.
