About this 0.88ct lab-grown cushion diamond

This 0.88ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG833636916 or 833636916. Listed at 18 retailers as of November 4, 2026, with prices from £300 to £1,260, a £960 spread on the same certified stone. Riddles Jewelry lists it at £1,260. 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.
