About this 0.85ct lab-grown cushion diamond

This 0.85ct lab-grown cushion sits in the just-under-one-carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG611359550 or 611359550. Listed at 17 retailers as of October 25, 2026, with prices from £220 to £918, a £699 spread on the same certified stone. Reve Diamonds lists it at £918. 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.
