About this 0.75ct lab-grown cushion diamond

This 0.75ct lab-grown cushion sits in the just-under-one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG817639986 or 817639986. Listed at 8 retailers as of October 30, 2026, with prices from £143 to £1,057, a £914 spread on the same certified stone. MOH London lists it at £1,057. 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.
