About this 0.83ct lab-grown cushion diamond

This 0.83ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG756513620 or 756513620. Listed at 13 retailers as of November 1, 2026, with prices from £316 to £2,281, a £1,965 spread on the same certified stone. Do Amore Diamonds lists it at £2,281. 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.
