About this 1.02ct lab-grown cushion diamond

This 1.02ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG800663011 or 800663011. Listed at 25 retailers as of November 3, 2026, with prices from £239 to £1,889, a £1,650 spread on the same certified stone. Do Amore Diamonds lists it at £1,889. 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.
