About this 1.23ct lab-grown cushion diamond

This 1.23ct lab-grown cushion sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG522229795 or 522229795. Listed at 8 retailers as of November 4, 2026, with prices from £212 to £1,682, a £1,470 spread on the same certified stone. Do Amore Diamonds lists it at £1,682. 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.
