About this 0.94ct lab-grown cushion diamond

This 0.94ct 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 LG816662487 or 816662487. Listed at 19 retailers as of October 30, 2026, with prices from £306 to £1,973, a £1,667 spread on the same certified stone. Diamond Exchange Canada lists it at £1,973. 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.
