About this 3ct lab-grown cushion diamond

This 3ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG629491666 or 629491666. Listed at 22 retailers as of October 30, 2026, with prices from £1,049 to £10,730, a £9,681 spread on the same certified stone. Yadav Diamonds lists it at £10,730. 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.
