About this 0.73ct lab-grown cushion diamond

This 0.73ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG733532099 or 733532099. Listed at 16 retailers as of November 2, 2026, with prices from £224 to £1,031, a £807 spread on the same certified stone. Reve Diamonds lists it at £1,031. 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.
