This 1.05ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG741516402 or 741516402. Listed at 19 retailers as of October 30, 2026, with prices from £116 to £1,105, a £989 spread on the same certified stone. Do Amore Diamonds lists it at £1,105. 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.
