This 1.2ct lab-grown radiant sits in the classic one-carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG625480580 or 625480580. Listed at 14 retailers as of November 4, 2026, with prices from £152 to £1,304, a £1,152 spread on the same certified stone. Do Amore Diamonds lists it at £1,304. 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.
