About this 0.43ct lab-grown cushion diamond

This 0.43ct lab-grown cushion sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG747545457 or 747545457. Listed at 13 retailers as of November 1, 2026, with prices from £177 to £991, a £814 spread on the same certified stone. Zales lists it at £991. 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.
