About this 1.03ct lab-grown radiant diamond

This 1.03ct lab-grown radiant sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG605312121 or 605312121. Listed at 17 retailers as of October 31, 2026, with prices from £146 to £1,134, a £988 spread on the same certified stone. Do Amore Diamonds lists it at £1,134. 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.
