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 VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG776611211 or 776611211. Listed at 17 retailers as of October 27, 2026, with prices from £156 to £1,403, a £1,247 spread on the same certified stone. Queensmith lists it at £1,403. 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.
