About this 2.9ct lab-grown cushion diamond

This 2.9ct lab-grown cushion sits in the two to three carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG836603096 or 836603096. Listed at 13 retailers as of October 30, 2026, with prices from £1,143 to £7,577, a £6,434 spread on the same certified stone. Do Amore Diamonds lists it at £7,577. 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.
